The moose video, WAS a .40 brother. lol . OP was CRaptor here on youtube in which he stated it was a factory stock g23, with golddot's, that indeed was a G23. .40 is awesome.
The 10mm was NOT developed for the FBI. It was a developed at the urging of Jeff Cooper by Norma as the ultimate “replacement “ for the 45ACP. Dornas and Dixon made the first pistol for it, the Bren 10, which was a beefed up CZ75. This all happened well before the Miami shootout which is the incident that drove the FBI to look for a more powerful round for agents to carry. The 40S&W on the other hand…
I've watched so many of your videos where you specify that there is no ammo in the room while you are making a video. But, of course, this one is about the ammo, so it makes sense. And everyone knows how safety conscious you are.
What do you mean by “designed for it“? A 10 mm can obviously handle the pressure in the chamber. There’s not enough of a difference in the length between the 40 Cal and the 10 mm to make a difference. The thickness of the projectile is the exact same. The twist rate of the barrel is the same even though that wouldn’t make a difference between the different rounds. This is just a way for him to sell product. But that’s OK. Yay for capitalism!
GREAT video! Agree with everything you said, but the section on barrel lubrication can not be overstressed. Failure to do this can and will result in a non-functional pistol until performed.
I am curious when the Gen 5 conversion comes out if you will sell the G20 as 40S&W conversion package and roughly what that will cost. If reasonable i may just make the trip from Knoxville for that.
More Earhart Click Bate. 1: Earhart and Noonan did not know Morse Code (could not understand the transmissions from the USCG Itasca). 2: Earhart took off the "radio directional antenna" (could not hear the direction of the Morse Code). 3: Noonan miscalculated location from being on the south side of the equator. 4: No water on Gardner Island (Nikumaroro) to survive. 5: Noonan may have been kill by sharks on Gardner. The large gas tank on the Electra caused the plane to float long distances before sinking.
Good point. Though not recommended, it definitely works. The cartridge is not correctly positioned, as the chamber of the 10mm is too long. It‘s mainly held in place by the extractor. So, don’t do it, … but it works 😉
"NOTE" Actually right now 10mm ammo prices on some brands has come down a lot. And I have seen a lot of 10mm cheaper than than 40 S&W many times lately. Since 40 S&W has become the "Not for the Cool Kids caliber" and kicked aside. So 40 S&W is not being as massed produced as it was it now costs more.
I can do something similar, I have a Para P14 in .45 yet I have a barrel that drops in that is chambered in .400 COR BON. Both have good stopping power.
But not ALL, Especially NOT the Self Defense or Hunting Loads. And its more of a concern of the head spacing. Its not going to effect the shorter 40 cal. Its going to effect the longer 10mm. We (in the Gun Smithing World) have seen 10mm severely damaged and destroyed do to just this issue. We aren't talking about 9mm target rounds. We're talking about HIGH PRESSURE +P+Rounds going off unsupported or in worse case even out of battery. This isn't like accidentally running a 380 ACP round or a 9mm Makarov into a 9mm luger. As it was explained to me by Dennis at S&W in Ballistics, Its like putting a 5.56 round in 9mm and pulling the trigger. "Its all bad when it goes bad"
I am skeptical about those mags, I shoot a Ruger Security-380, which is literally a rechambered Security-9, withe the 9mm mags, and there is a 2mm spacer in the magazine
Good and informative video. I was in there last week and it is a beautiful place and the staff are very friendly and helpful. I have a question. Can a G19 Gen 5 slide work on a G19 Gen 4 lower?
You can shoot .40s&w out of a glock 10mm pistol without changing anything. I have done this many times without any failures!!! No need to get .40s&w barrel.
The upgrade Allows you ?🤔.... I have been doing so for Years... With No issues... With No upgrade... And just as accurate 👍😎🇺🇸🇺🇸🇺🇸 1. But to be clear... I Also have Never owned a Glock... 2. The so - called extractor issue has Never been an issue... Never,the extractor still works as it should with the .40 rounds 👍😎
I love it. Everyone belittles 40 S&W and elevates the 10 mm to be the greatest thing since sliced bread. Only to then get a 40S&W conversion for their 10 mm. Truly rich.
Anyone doing this is only doing it to save a few dollars at the range . Nobody is doing it to actually carry it . I like the 40 cal round but would never carry it in my 10mm . Target practice only
Man, I don't know where the economy is with 10mm vs 40 cal? Miniscule difference. By the time you pay for another barrel and then you're practicing with a round that isn't the same as your main carry? What's the economy or efficiency with that? I don't get it? I don't like it but , for me anyway, I just suck it up and pay the price for 10mm. Then, I know I'm ready for whatever life throws at me. 10mm, even full powerhouse loads no big deal. After shooting/carrying 44 mag most of my life 10mm is like a breath of fresh air. Plus 3+ times the firepower. I'm glad 10mm is gaining popularity. Maybe prices for ammo will get better soon?
@@jugulartara4388 a few 10s shoot it well and accurately. Glock is one of them. I carried 23 for a couple years in law enforcement then switched to the 10mm version and carried 40 cal ammo in it but also had 10mm loaded in mags as well if needed.
You would have to change it back for 10mm. The .40 S&W chamber in the conversion barrel isn't deep enough to allow the 10mm to fully seat in it. The primer end of the 10mm cartridge will stick out of the chamber and the slide will not be able to close all the way.
The recoil from the 10mm or 40sw is no big deal. People and officers who said they could not shoot it well were because they could not shoot to begin with. Secondly, the reil is not painful in a pistol, snappy but not painful.
In 7:20 "If the 10 mm to .40 S&W barrel are basically the same diameter" Why don't make a conversion kit from 10mm to 9mm or 357S&W? The .40S&W to 9mm or 357S&W conversion kit already exist; Someone knows if using a 40S&W to 9mm conversion kit barrel on a 10mm create a ejecting problem?
You can always go down in caliber from a higher caliber Glock, but NOT the other way around. So a 45 cal Glock can run conversion barrels from 40, 357, 9mm etc. So in essence buying the highest caliber Glock that you'll ever want to shoot has the MOST value because for not much more money you can convert them to whatever other caliber you'd like WITHOUT buying the extra firearms. Go look at other after market Glock conversion barrel makers as well. I bought a 40cal to 9mm conversion barrel from Aim Surplus for $50 & the same exact barrel but with blemishes for $30. I can't even see where the supposed blemishes are but they work fine. So for well under $100 I bought a barrel & a 9mm magazine & have myself a 9mm Glock now & it's essentially an unregistered ghost gun.
jimchambers It's called Cash Cow, Bank Roll. This man has made a lot of money off Glocks and more so aftermarket parts. There's many people that shoot 40 out of the 10mm without changing the barrel. Bank Roll as he laughs all the way to the bank.
@@arlissyoung8899Wrong...... I love you guys think its all about a dollar. Because you clearly don't know 💩💩💩💩💩💩💩 about guns. Because if you did, You would understand how straight wall pistol cartridges HEAD SPACE off the mouth of the cartridge. And what happens when you get BUILD UP or DAMAGE to this area in the chamber. The 40 round isn't going to be the problem. However the 10mm WILL BE. Don't believe me??? Call the company that made the 40cal. Smith&Wesson. Ask for Dennis in Ballistics, He'll be happy to explain it to you. And show you chamber dimensions and pics of what happens when it goes bad.
Hey my friend, Very good question. And here's where you will find the answer. It's called "Head Spacing" straight wall pistol rounds like the 40 cal. and 10mm (And others) head space off the mouth of the case. You can call S&W who came out with the 40cal. And talk to Dennis there in Ballistics (or anyone elese) They will explain it to you in depth on why you DO NOT WANT TO DO THIS. If it was me and in a life or death situation, Thats one thing. But ONLY in that situation. Its not like shooting 38's in a 357 as others that are less informed think its fine to do. PLEASE DO THE RESEARCH AND IF YOU STILL AREN'T SURE. CALL THE PPL PROFESSIONAL THAT MADE THE ROUND, Smith & Wesson. They'll be more than happy to speak with you about this issue.
I have already converted my G22 Gen4, into 9mm. I noticed that you did not talk about the ejector, the difference between the two, and why it is important to change the trigger frame accordingly.
No. The slide is made for a 9mm dimension barrel. Mainly, the hole in the front of the slide. You need a 40S&W dimension slide and barrel. The 357Sig is based on a case of similar size to the 40, only necked down to 9mm. I guess you could get a different slide for your frame.
That's not a Glock barrel. It's an aftermarket. Glock will make you spend more money than you need by making you buy a whole other gun to change calibers.
I'm scratching my head a bit over how the industry feels there is consumer interest for a 10mm to .40 S&W conversion barrel, but there is no interest for a 10mm to .40 S&W conversion magazine. I'd feel a lot better knowing the ammo won't be getting jarred forward and out of sorts in the stack eventually leading to a feeding malfunction.
Lenny...please put the plastic tip back on the needle of the Gun butter bottle...you're making me nervous with your arm movement near the bottle. Otherwise, outstanding video!
Lenny, Would you PLEASE do another video and have someone from Smith & Wesson on with you (The company that invented the 40 cal. SMITH & WESSON) And explain TO CERTAIN INDIVIDUALS in the comments in this video of WHY IT IS IMPORTANT NOT TO FIRE 40 CAL AMMUNITION THREW THE 10MM chambered barrel. And how the straight wall pistol rounds HEADSPACE off the mouth of the case. And what can happen when a "Out of Battery Detonation" happens due to a damaged 10mm barrel from shooting 40 cal AMMUNITION threw it. Thank You Sir.
You mean please get some lawyers to come on and run their mouths about how shooting it out of your gun is not supported and don’t blame us if anything happens.
Apparently you don't know how it works. You cannot get an out of battery detonation. If for some reason the .40 round gets in front of the extractor it will not go off. If the slide doesn't fully go into battery it will not fire. The only negative byproduct is a little extra effort to clean possibly a little less accurate. The pistol will not add cannot blow up. I've shot 1,000's of factory and reloads in my Glock 20 and 40 without issue. Please do actual research on the subject before you comment about shit you have zero clue about. I have had a case blowout in my old Gen 3 Glock 22 and Gen 4 17. The only thing that happens is the mag gets blown out of the bottom and a superficial powder burn on your hand from gasses blowing out of the mag release.
Well because when you watch the video thats a live round going in the barrel he has in his hand. Plus you can see the live primer in the case. If you reload then you know the difference of a case with no primer a fired primer or no primer at all. I mean i do cause i reload as well. @@wyomarine6341
California law is pretty iffy. Now would this violate any law in California? I mean due to the fact that when purchasing a firearm. The caliber of the purchased handgun is also registered or recorded.
@@duckwacker8720 at this point anybody whith a gun is a crimminal and thus im allowed to have one in california, just keep it a secret and wear a mask like the rst of the crimminals.
My Glock 20 doesn't care, I've never had a malfunction... Shoots 40 Cal just fine, and with the bigger gun, the G 20... And you'll have far less recoil with the G 20
You don’t need shit to do this. The Glock pistol headspace’s off the breach face and therefore will work safely. If you shoot weaker loads you may need a weaker spring.
So realistically……. Buy a Glock 21 which is a .45 ACP and then buy a Glock 20 conversion barrel. Then I can shoot 10 mm, .40 S&W and maybe SIG .357 all from the same barrel. That’s 4 calibers from 1 firearm. Now if you want to make a 5th one, buy the .22 Luger slide for the Glock 21 too and now you have 5 calibers.
Dont pay for a barrel swap.....40SW is perfectly fine and safe to shoot out of your 10mm same as shooting 38spc out of a 357 firearm. This is just getting you to buy a product you dont need
2 Small dangers of shooting 40 out of a 10mm barrel - breaking your extractor because that's what's holding the brass instead of the throat and secondly- getting metal shavings out your barrel - the bullet shaves off tiny amounts of metal as it passes the throat rings meant for the 10mm brass. Some gun ranges don't like you shooting "shot" shells as there is a greater chance of bounce back, most don't care, but be aware you are shaving your bullets and shooting fragments. There may also be a chance of lead build up on that ring so when you go back to 10mm it may not seat well forward enough.
The extractor isn't going to break. The millisecond from the striker hitting the primer and the round going off doesn't have enough forward force to do any damage.
No one really needs a Glock now days. The gun market has moved far beyond the stuck in the 80s. There's far better guns on the market now days as Glock stayed the same as it did the day it hit the market sadly. Technology upgrades to Glock is Optics and front slide cuts, now that some upgrades right there.
These barrels won’t sell lol. Everyone knows you can shoot .40 cal in a G20 lol 20SF or 29. These mfs will do anything to sell an unnecessary product. If they wanna fix something they should look at walther PDP and take notes.
This is what you call having no shame. Flat out lying and spreading misinformation in order to shill a product. SHAME ON YOU. I’ll be sure if I ever do need some parts, to not get them from your business.
Most 10mm loads are loaded to 40S&W specs till you get into Buffalo bore, hard cast but even then 40+p is basically the same.. Not an upgrade because it's the same
@@duckwacker8720 Wym people complain that regularly 40s&w and 10mm doesn't penetrate vital organs good enough on larger targets. Since guy implied 40 isn't an upgrade I simply stated it's the same thing until you get into specific loads that have more power and harder castings.. not to mention it's way cheaper to buy ammo
Harrel just shot 100 rds .40 from a 10 mm G 20. No misfires or issues.
I trust that guy for sure
i shoot 40cal out of my glock20 10mm everyday without changing the barrel
That's what Im saying... This is just their way of MAKING you spend more money... Smdh 😒😒😒
Overtime won’t you damage the barrel ?
No it won’t damage barrel it’s like shooting .38 special out of a 357 magnum
The barrel in the conversation is just gonna have a longer feed ramp and maybe a little tighter as well but yeah G20 stock will work
A 40 actually gets more chamber support in a ten...
The moose video, WAS a .40 brother. lol . OP was CRaptor here on youtube in which he stated it was a factory stock g23, with golddot's, that indeed was a G23. .40 is awesome.
I could listen and watch Lenny talk about Glocks all day long. Luv u Lenny. Ur a good dude.
The 10mm was NOT developed for the FBI. It was a developed at the urging of Jeff Cooper by Norma as the ultimate “replacement “ for the 45ACP. Dornas and Dixon made the first pistol for it, the Bren 10, which was a beefed up CZ75. This all happened well before the Miami shootout which is the incident that drove the FBI to look for a more powerful round for agents to carry. The 40S&W on the other hand…
Also , before there was the 40 sw , there was a downloaded 10 millimeter called the fbi load.
I've watched so many of your videos where you specify that there is no ammo in the room while you are making a video. But, of course, this one is about the ammo, so it makes sense. And everyone knows how safety conscious you are.
I own both 10mm and 40S&W Love them both. They can stop what’s bothering you.
You can already shoot 40 out of a 10mm Glock without issues but if your going to do it on the regular having a barrel designed for it makes sense .
What do you mean by “designed for it“? A 10 mm can obviously handle the pressure in the chamber. There’s not enough of a difference in the length between the 40 Cal and the 10 mm to make a difference. The thickness of the projectile is the exact same. The twist rate of the barrel is the same even though that wouldn’t make a difference between the different rounds. This is just a way for him to sell product. But that’s OK. Yay for capitalism!
@@TheAxe4Ever Paul Harrels brother just proved your case.
@@TheAxe4Everwrong
@@johnpoole8321 He did not prove it. There is a reason (and no its more than just a legal reason) the 10mm Glocks don't say 10mm AND 40sw on the side.
Appreciate the tutorial
Most current factory production 10mm is loaded to the same velocity most factory 40cal is loaded to.
I keep seeing people say that but the majority of 10mm ammo I see is loaded to 9mm velocity which is about 100fps more than most typical 40 s&w ammo
We all know what is going to happen in the video but we must watch every second of Lenny no matter what
Definitely not.
Congratulations from Brazil
Thanks for the 411!
Thanks Lenny
Yea I saw that video of the person shooting at the moose
I have yet to see a recent loading for the 10mm caliber that exceeds what the 40 cal is capable of in a proper loading for its case capacity.
GREAT video! Agree with everything you said, but the section on barrel lubrication can not be overstressed. Failure to do this can and will result in a non-functional pistol until performed.

There's no reason for a different barrel.
Okay my question is if I can shoot 40 out of my 10 mm with a barrel switch can I shoot 10 mm out of my 40 with a barrel switch ?
No, the 40 glocks are 9mm frames and not designed for real 10mm power. 10mm guns are built on 45 frames. Also 10mm won't fit in 40 mags.
Ok, how about the other direction?
You don't need a conversion barrel to shoot .40. Just use the factory 10mm barrel.
I've noticed on these YT tests it appears the 10mm looks to be watered down except for certain ammo companies ...
It is, most companies load them to the same specifications as the .40sw I believe.
It is. Check out Tools and Targets on RUclips. He is a big 10mm fan. Most companies are just charging extra for 40 in a 10mm case.
Conversion barrel isn't needed lol so many people already shoot 40 s&w from there 10mm guns
What about a 40 S&W 6” barrel?
Kkm makes one. I bought one and never use it. Wanna buy it? Lol
I have already converted my G22 Gen4, into 9mm.
I noticed that you did not talk about the ejector, the difference between the two, and why it is important to change the trigger frame accordingly.
Because going from 40 to 9 is not the same as shooting 40 out of a ten.
.40 to 9mm is the stupidest conversion ever.
Will it work in the new G29 gen5?
Yea I got the gen 5 29 and put 50 .40 rounds through it no issues
Is there anyway I can convert my Glock 17 to a G 31?
No. The slide is made for a 9mm dimension barrel. Mainly, the hole in the front of the slide. You need a 40S&W dimension slide and barrel. The 357Sig is based on a case of similar size to the 40, only necked down to 9mm. I guess you could get a different slide for your frame.

That's not a Glock barrel. It's an aftermarket. Glock will make you spend more money than you need by making you buy a whole other gun to change calibers.
@@rudyschwab7709that's what I do, but I also shoot .40 in my 10mm's.
I'm scratching my head a bit over how the industry feels there is consumer interest for a 10mm to .40 S&W conversion barrel, but there is no interest for a 10mm to .40 S&W conversion magazine. I'd feel a lot better knowing the ammo won't be getting jarred forward and out of sorts in the stack eventually leading to a feeding malfunction.
It doesn't
Does a 1911 headspace off tje breach face? G. K. U.S.A
different calibers without investing in multiple guns
Fail
.45 cal is 11.43mm
they need to make one for the long slide G40 thats the cool one
A G 24 barrel should work in the G40
@@keithwelch8563there's no reason.
Lenny...please put the plastic tip back on the needle of the Gun butter bottle...you're making me nervous with your arm movement near the bottle. Otherwise, outstanding video!
Can a 10mm barrel work in a G22?
Nope
If only there was a way to shoot .357 sig in a .40 or a 10mm.
Buy a 357 Sig Glock barrel and put it in your 40 S&W Glock slide. Fits and works perfectly.
Lenny, Would you PLEASE do another video and have someone from Smith & Wesson on with you (The company that invented the 40 cal. SMITH & WESSON) And explain TO CERTAIN INDIVIDUALS in the comments in this video of WHY IT IS IMPORTANT NOT TO FIRE 40 CAL AMMUNITION THREW THE 10MM chambered barrel. And how the straight wall pistol rounds HEADSPACE off the mouth of the case. And what can happen when a "Out of Battery Detonation" happens due to a damaged 10mm barrel from shooting 40 cal AMMUNITION threw it. Thank You Sir.
You mean please get some lawyers to come on and run their mouths about how shooting it out of your gun is not supported and don’t blame us if anything happens.
Apparently you don't know how it works. You cannot get an out of battery detonation. If for some reason the .40 round gets in front of the extractor it will not go off. If the slide doesn't fully go into battery it will not fire. The only negative byproduct is a little extra effort to clean possibly a little less accurate. The pistol will not add cannot blow up. I've shot 1,000's of factory and reloads in my Glock 20 and 40 without issue. Please do actual research on the subject before you comment about shit you have zero clue about. I have had a case blowout in my old Gen 3 Glock 22 and Gen 4 17. The only thing that happens is the mag gets blown out of the bottom and a superficial powder burn on your hand from gasses blowing out of the mag release.
Superfluous
I think this is more practical if you intend to shoot 10mm or 40 out of a Glock 21 🤷🏽♂️
Second time he's worked on a glock with ammo in the room. He always said he never works on a gun with ammo in the room.
This is true
Turn in your man card...
Turn in your man card? Why?@@michaelphillips5786
Well because when you watch the video thats a live round going in the barrel he has in his hand. Plus you can see the live primer in the case. If you reload then you know the difference of a case with no primer a fired primer or no primer at all. I mean i do cause i reload as well. @@wyomarine6341
. 40 cal is 9.1mm
California law is pretty iffy. Now would this violate any law in California? I mean due to the fact that when purchasing a firearm. The caliber of the purchased handgun is also registered or recorded.
Nobody gives two shits about Commifornia.
@@duckwacker8720 at this point anybody whith a gun is a crimminal and thus im allowed to have one in california, just keep it a secret and wear a mask like the rst of the crimminals.
My Glock 20 doesn't care, I've never had a malfunction... Shoots 40 Cal just fine, and with the bigger gun, the G 20... And you'll have far less recoil with the G 20
Can't you see he's making Bank Roll here, the shepole will gladly hand over their hard earned money because Lenny said so.
@@arlissyoung8899Dude,You and your STUPID WRONG ADVICE are going to get someone killed.
nice to know, thanks
You're Welcome... I did buy a 9 mm barrel for my G23 so I could shoot the other cal... 9mm@@MegaCyberleader
You don’t need shit to do this. The Glock pistol headspace’s off the breach face and therefore will work safely. If you shoot weaker loads you may need a weaker spring.
10mm is .39 cal
Why use a different barrel? I shoot 40 short & week out of my Glock 40 all of the time with ZERO issues……. This doesn’t really make sense…
It's too make him money.
So realistically……. Buy a Glock 21 which is a .45 ACP and then buy a Glock 20 conversion barrel. Then I can shoot 10 mm, .40 S&W and maybe SIG .357 all from the same barrel. That’s 4 calibers from 1 firearm. Now if you want to make a 5th one, buy the .22 Luger slide for the Glock 21 too and now you have 5 calibers.
he keeps saying they are close diameter. no they're exactly the same.
Dont pay for a barrel swap.....40SW is perfectly fine and safe to shoot out of your 10mm same as shooting 38spc out of a 357 firearm.
This is just getting you to buy a product you dont need
2 Small dangers of shooting 40 out of a 10mm barrel - breaking your extractor because that's what's holding the brass instead of the throat and secondly- getting metal shavings out your barrel - the bullet shaves off tiny amounts of metal as it passes the throat rings meant for the 10mm brass. Some gun ranges don't like you shooting "shot" shells as there is a greater chance of bounce back, most don't care, but be aware you are shaving your bullets and shooting fragments. There may also be a chance of lead build up on that ring so when you go back to 10mm it may not seat well forward enough.
I wouldn't make common practice out of it, but it's good to know it can be done in a pinch.
The extractor isn't going to break. The millisecond from the striker hitting the primer and the round going off doesn't have enough forward force to do any damage.
@duckwacker8720 well, they do and have...opinions aren't reality.
Dude needs to stop smoking. That voice even sounds like tough leather

You can't afford 10 mm ammo then you don't need a Glock
No one really needs a Glock now days. The gun market has moved far beyond the stuck in the 80s. There's far better guns on the market now days as Glock stayed the same as it did the day it hit the market sadly. Technology upgrades to Glock is Optics and front slide cuts, now that some upgrades right there.
What about 9mm conversion for 10mm?
Stupid.
These barrels won’t sell lol. Everyone knows you can shoot .40 cal in a G20 lol 20SF or 29. These mfs will do anything to sell an unnecessary product. If they wanna fix something they should look at walther PDP and take notes.
I shoot 40 out of my glock 29 all day. This is bull. Spend what ya want. Clean your weapon and move on
This is what you call having no shame. Flat out lying and spreading misinformation in order to shill a product.
SHAME ON YOU. I’ll be sure if I ever do need some parts, to not get them from your business.
Lies you dont need no kit 😂😂😂
Why would you want to do that
F Glock
PSA: going from 10mm to .40S&W is...
not a 'upgrade'
till you pay for a case or two of ammo
Most 10mm loads are loaded to 40S&W specs till you get into Buffalo bore, hard cast but even then 40+p is basically the same..
Not an upgrade because it's the same
@@trilliamogdlocog4986hardcast had nothing to do with it
@@duckwacker8720 Wym people complain that regularly 40s&w and 10mm doesn't penetrate vital organs good enough on larger targets.
Since guy implied 40 isn't an upgrade I simply stated it's the same thing until you get into specific loads that have more power and harder castings.. not to mention it's way cheaper to buy ammo
@@duckwacker8720 but I digress if you didn't get it after I explained ain't nun I can do
Lol I already can, don't buy this gimmick
