Your channel is one of the very few on RUclips to provide such high quality 10mm content. Keep up the great work!!!
Glad you enjoy it!
I carry a 20 in the woods. Love that gun. There's a real feeling of safety with a 10mm in the trees.
👍🤠
I carry a G40 Gen 4 in the wilderness all the time loaded with Buffalo Bore 10mm.
That gun is thermonuclear cool.
No doubt, gotta be careful around those T Rex's cruising the woods
@@billybenson3834 that was actually hilarious, all jokes aside, I carried a 45 in the woods for the longest time. I live on the east coast, so no brown bears. Heard stories of bears in in Canada get killed at 800 plus lbs. When someone killed a 700 lb black bear in nj where I grew up, and always hung around in the woods. My ass ran out and got a glock 20 real quick
@@andog6092 even 45. Could take bear, if it came down to that. And if you had the combination of good aim and the right load. Underwoods 255 hard cast keith 45. Is my go to woods load. It hits the steel hard as hell and seems to run well. 10mm would be better. But the 45. Ain't dead yet.. don't believe the hype.
If all the videos on this channel have this quality, I think I hit a gold mine. Very underrated channel.
Appreciate that!
I've had a Para LS Hunter Elite 6" for years now. I luv it. Harvested 3 whitetail with it so far .
Excellent!
I always believed the 10mm and the 1911 platform is the perfect marriage. Even though I am a wheel gun fan the 1911 is one awesome pistol that has proven the test of time!
Yes indeed.
I agree, love revolvers.
Go get yourself a S&W M-610, its also shoots 40s and utilizes moon clips.
If only my old (now sold) Kimber Eclipse would have ran more than 2 rounds without jamming. Luckily have a Glock 20 without said issues.
The new standard for a 1911 is 10mm as it should be. I hope it consumes the 1911 market also
If you look at the ballistic tables, the 10mm with a 180 grain bullet has the same energy at 100 yards that a 45 ACP firing a 230 at 800 FPS has at the muzzle.
👍🤠
I would love a 10mm but the power they have worries me. I carry a .45acp 1911 because of the reason you stated above. If something ever happened and I miss the shot I don't want the bullet to have that much energy. Even if you don't miss it could still over penetrate.
@@Nefarious_BreadSo try frangible ammo👍
@@Nefarious_Breadit very rarely ovepenetrates energy doesnt mean penetration
45 ACP for anything on two legs 10 mm for anything on Four
You’re the best. My old hands just talked me into my 1st 9mm 1911 and you’ve got to raise the bar again. I’m in awe.
👍🤠
I bought a Razorback about a month ago as my first 10mm. I'm still breaking it in and have had a few failure to feed issues. It was worse the other day, but seemed to get better today. I just hit 300 rounds.
I'm so glad I watched this video. I just bought a Glock 20 (haven't even picked it up yet) and have already started reloading for it. I guess I'll be barrel shopping too now. Thanks for the information, it's appreciated.
My pleasure.
I bought a Glock 20 a few years back after doing extensive research into 10mm. The first time I took it to the range I absolutely loved it, that sharp recoil really impressed me and seeing how hard it hit made me a big fan of the caliber. I also have 2 Taurus revolvers with 6 inch barrels, one is chambered in .357 magnum and the other is chambered in .44 magnum, even though I like shooting them both, my go to gun for home defense, everyday carry and hunting is my Glock 20 because it is so darn fun to shoot. I think that 10mm is such a beast of a round with great combination of ballistic performance and impressive power. I am definitely not sorry for going to the 10mm.
👍🤠
Agree 100%. I’m a huge 10mm fan. Have been for many years. Nothing like a sledgehammer round in a Glock semi auto!
@@jasonlommen4769 I really get annoyed with the 9mm fanboys that claim that 10mm is a niche round. My response to those fools is that 10mm is here to stay, and it isn't an outdated caliber like 9mm.
@@bdr32965
I agree! Too many wimps out there who cannot handle the 10mm cartridge. I love it’s versatility and power. My Glock 40 is my dresser/woods gun and the G29 is my daily carry. I don’t mind shooting 9mm as I have a few Glocks in that caliber, but 10mm is my fav pistol round ever and my go to. Happy shooting my friend, stack it deep!
@@jasonlommen4769 I'd love to get the G40 at some point, but first I want to get a 1911 chambered in 10mm. I agree about some shooters being either afraid of 10mm or unable to handle that hard snap, but I love the feel of that snap. With the magnums and even .45 ACP you have that pushback before the barrel rise, which after a while starts causing the grips to dig into your palm. But that hard upward snap of both .40 S&W and 10mm seems to add something to the experience. As far as the 9mm fanboys saying that 9mm is easier to get back on target I call bullshit, because after I got proficient with 10mm it's easy for me to mag dump as quick as I can with 9mm, and can even do it with 1 hand.
Attended an NRA reloading class in early 2000, best thing I have done in regards to weapons!
👍🤠
Another excellent video. 10mm is not for beginners, but info like this will help educate and keep the popularity of the 10 growing..Subscriber list keeps on growing, I can see why!
👍😉
What I've learned about 10mm pistols: I wish HK made one.
👍
Me too I converted my usp40 to take 10mm
@@babyblue0713 Wow how'd that turnout?
@@jimlamanna7564 it’s really nice ruclips.net/video/wzh16zi55G0/видео.html here’s how I did it
Another USP 10 guy here. Really easy to do.
Glad to see you're still putting out new videos!
👍🤠
Started my 10mm collection with a Ruger Match Champion, them a Kimber Eclipse 2....then a S & W 610....now a Glock 20 with a KKW SS Barrel....I love that round. Perfect combo of punch and straight trajectory and accuracy.
👍🤠
I could listen to you all day long. Love your voice and your videos. God bless.
Wow, thank you!
Got to be the Best 10mm collection in the country. I haven't seen anyone that to you. Wow
He who dies with the most 10mm's - wins!
I was one of the first people to buy a Delta Elite and have been shooting it regularly ever since, always with my own reloaded ammo. I shoot full-power loads exclusively-I have. 45 Gold Cup when I want to shoot light target loads. As long as you don’t decide to get creative with your reloads, and instead respect responsible loading data, an unramped unsupported barrel will have NO issues whatsoever. I am literally shooting the same brass I first started using back in about 1987, with no failures worth mentioning in all that time. 10.0 to 10.4 grains of Blue Dot behind a 180 grain bucket is certainly no slouch. It’s not as hot as the crazy Norma factory ammo (which arguably was way over pressure) but it’s certainly hotter than the weak 10mm factory ammo of today, which for the most part is just 40 S&W in a longer case rather than true 10mm auto.
I agree. Some people have a tendency to load their 10mm rounds a bit too hot. This, by itself, will shorten case life considerably.
Love Blue dot for 10's and 44 mag.
I actually bought a Sig P220 Legion in 10mm after watching your videos, and it’s safe to say it’s become my favorite handgun that I own. An absolute tank that thing is, handles the hottest reloads I throw in there, and due to its weight the recoil impulse honesty feels similar to a .40 S&W. Now just waiting for the day they release an extended magazine haha
Yeah, more bang for the buck!
I feel like the 10mm recoils harder than the.40 but it doesn't jump up as much if that makes sense
Concise and straight to the point. Thanks for the information sir!
My pleasure. 👍
Well explained and detailed presention. No bad mouthing just facts. Big thumbs up!
Thank you William!
I bought my Delta Elite used in 1990 and been a huge fan of the 10mm since then. I've put a couple thousand rounds through it. Most of those have been my own very hot reloads without any issues. Only upgrades I've done to the gun is a full length guide rod and a very heavy recoil spring. I guess I've just gotten lucky so far. I do have a G20 but only use factory ammo in it. I will look into a lone wolf barrel for it. Thanks for all your info.
My pleasure John.
Extremely informative for someone looking into a 10mm for the first time!
Best to ya',,,,!
Thanks, you too!
Thank you for sharing so much knowledge my man!
My pleasure!
Just great to see another video from you! Thanks a ton!
My pleasure!
I glad someone finally mentioned in a video, colt delta elite lack of chamber support . I personally found this out through forums a few years back . After buying and collecting many colt deltas really liked them but sold them for better choices . I wish colt would have addressed this in their later productions . I heard & read about glocks lack for years that info was everywhere but not colt it was like a secret. Thanks for your video!
My pleasure!
It’s never been a “secret.” Just looking at a Delta Elite’s barrel and one can see that it lacks full chamber support. It’s no big deal when shooting factory ammo that isn’t loaded up to over pressured “nuclear tipped” 10mm ammo. Too many people want such hot rounds, they blindly will take a 10mm case and try to morph it into “.50BMG “ pressures. Think: DoubleTap, Underwood and even Buffalo Bore, who produce ammo that really beats the s*** out of one’s frames, slides and chambers. I tell people that if you want something with more “BANG,” than factory standard 10mm loads, then why don’t you just buy “more gun” like a .44mag or Desert Eagle 50???
I thought they fixed it by now.
Colt delta elites are worthless compared to others.
The reviews here are always excellent!!!
Thanks Fred.
I Am A Long Time Competitive Bullseye shooter And Most Of My 45's Are From Clark Custom Guns. Back When The Delta Came Out; I Bought One And Almost Immediately Called Jim Clark Sr. And Arranged To Send Him My Colt. I Use Nothing, But FULL Power Max Energy Loads With The Delta And Have Never Had A Problem. My Pistol Was Set Up And Maxed Out Like He Does His Bullseye Offerings.
Problems sometimes occur when cases have been reloaded a number of times. With new cases, it usually isn't an issue.
Great video Sir! I love that Lone Wolf barrel on your Glock and your taste in grips is amazing. Please keep the videos coming!
👍🤠
Thank you for this video. This is information that I did not know and am glad I know now since I've been thinking about getting a 10mm pistol.
👍🤠
Get you a Glock in 10mm and a TNW ASR in 10mm. That combo is amazing. Both guns use the same ammo and the same mags.
Too late, already did. You must not have seen my review on the TNW Aero 10mm carbine that I've already uploaded.
10mm is a fantastic choice, thanks for the reminder about chamber support!
👍🤠
The SIG P220 Legion is probably my favorite 10mm/handgun of all time. The weight of the factory slide and spring are the heaviest I have encountered in a (not-desert-eagle) handgun. This added weight and spring tension soaks up the recoil from high power factory loads (Underwood 220 gn) beautifully.
👍🤠
Yes. I got one of those too. It likes the hotter ammo because of the stiff spring, as I noticed on the last round of a magazine, the slide fails to lock open sometimes with some of the weak 10mm rounds (experienced it with Federal AE). Thats ok though. The reason I got a 10 instead of a .40 is because I wanted to fire the hotter rounds anyway.
Full-size Sig Sauer P220 10mm pistols with 5" barrels are some of the best designed, most powerful, highest quality pistols of all time. I have four - the stainless, Hunter, SAO, and DA/SA. 45 ounces of steel beauty, muscle, reliability, and accuracy. A 10 rating on a 10 point scale.
Just bought my first 10mm last month, Glock 20. I love it!
Nice!!
You forgot about the S&W 10mm born in the 1980's , one of best hand guns I ever had
Just because I didn't mention it, has little to do with the conversation or content.
Man I love your videos, very informative and you're just a pleasure to listen to. I'd like to see more content from your Channel
I upload as often as I can - mostly as time permits.
@@Icarryone I understand
Thank you for this informative video. I learned to replace my Glock 20 factory barrel with an aftermarket barrel, most likely a Lone Wolf.
👍🤠
Lock into KKM. Better barrels
Thats my round i carry 1 everyday - great video as usual sir thank you for your great advice - live long prosper well -
👍🤠
Springfield XDM 10mm 3.8" OSP shoots really nice. Beautiful trigger. Very accurate. Recoil not that bad, even with the Underwood bear killer loads.
👍🤠
First time I have seen any of your videos. Well done.
Thanks and welcome!
Love your videos. Love 10mm. I have a ruger 10mm and put the same grips and polished the barrel. Just like you. Keep up the great 10mm videos.
👍😎
Thanks that was very informative. I wasn't sure about 10mm and more importantly about the reloaded casings . 👍
Glad it was helpful!
Hi Sir glad to see your back to making videos I pray u and your family is doing well have a great day
Thank you Dexter, I will. 👍
Good information to think about. Thank you for sharing the information.
My pleasure.
More great info that only experience can speak to.
Thank you.
Great Video. With the current ammo climate we have to save our brass for future reloading. That is a no brainer. I am a revolver guy, LOVE LOVE me some 357 Magnum. I consider 9mm, 40 and 45 acp all compromises, but not the 10mm! What a great cartridge. Glock nailed their model 20, what a sweet shooter with that double op rod spring. Kudos to things that just WORK!
I am gonna order me a wolf barrel today.
👍🤠
10mm is my favorite round. I carry a Ruger GP100 3” in 10MM and I own 9 other pistols and 2 rifles in 10MM. It’s a great round. I wish more manufacturers made firearms in this caliber.
Agreed.
How does that 10 mm perform out of a rifle length barrel
I guess I'm lucky! My Ruger 1911 in 10 mm has no problems with reloaded ammunition. Great video keep them coming sir!
Your Ruger has all the right stuff!
I've seen the case head swelling out of my glocks, an its once fired factory brass, so it is a fact for glocks, but they are factory barrels. Didn't know the storm lake an lone wolf barrels would fully support the round, good to know. Thx for the vid
My pleasure!
Stormlake, Barsto, and KKM seem more supportive than Lone Wolf, but they're all more better than stock.
@@texasbeast239 I think Barstow makes the best barrels out of all, i have 20
I noticed that with the ejected cases from my Glock22. The swelling is minor but noticeable.
Greatly appreciate the information you shared as I just bought a Glock 29sf and plan to reload my 10mm brass. I had no clue about these facts. Thank you kind sir. I plan to get a 10mm 1911 next year at some point.
My pleasure Doug. 👍
I bought the Glock 40 MOS. It eats up the recoil from the 10mm very well. The longer slide helps out a lot
👍🤠
Impressive; to the point and easy to understand. Thankyou.
You are welcome!
@@Icarryone
I forgot to add; 1st time 1911 owner, 1st time 10mm owner...
My Specialist 10mm was having some issues at the beginning with some failures to feed. I didnt fully follow the break in process but cleaned and oiled very wll prior to shooting. Nor did I fully keep track of round count but ever since i got past around 500 rounds in my stash it really smoothed out with cleaning and greasing all contact points every 100 rounds about. Racking the slide and recoil feels much smoother than when it was brand new, like glass.
Great video as always.
Thanks, I appreciate that.
USEFUL INFORMATION. TO THE POINT. NO WASTED VERBIAGE. THANK YOU.
Glad it was helpful!
What an astute set of observations!
I had a Delta Elite and liked it pretty well but gave it up in favor of the .45 Super. I got one right after Dean Grennell introduced it in 1988.
While there may be some advantages to the Super because of heavier bullets the fact is that for most people the Super and 10mm are virtually interchangeable.
The real advantage of the Super was the guy building the gun.
Virtially the same criteria mentioned in the video and a few others having to do with the ejection port and extractor.
Ace Hindman was simply out building Colt because he understood what was needed to make the 1911 work with those high pressures.
I think it adds validity to the points made here.
Your comments about chamber dimensions were spot on as well.
I shoot some very heavy .45 Colt loads in revolvers. The old .45 will do anything the .44 Magnum will but at lower pressure. Case life and extraction are excellent even with heavy loads.
Those .45's started as .44's and were rechambered to minimum SAAMI specifications or cylinders built from scratch.
The published tolerance for the old Colt were wider than most cartriges and loose chambers were to blame for most head separations.
This useful fact was researched in depth by John Linebaugh and Ross Seyfried who popularized the idea.
I only mention it to support the content creators comments about chamber dimensions.
Fantastic content here.
Subbed and liked.
Cheers!
Appreciate the input.
@@Icarryone Appreciate your output!
You are touching on concepts that are really important if a person chooses to shoot a pistol with this performance potential.
This is especially true regarding handloading and chamber dimensions. You just enabled anyone considering a Glock 20 purchase to do so with an informed perspective.
Nobody should be considering purchasing a 10mm pistol casually.
Very few gunwriters seem to even be aware at this level anymore. I don't blame them, they simply write for the masses whose interests have shifted over the decades.
Again, great content!
Cheers!
10mm is a great cartridge . Just knowing its limitations as a reloader helps. The guns i have are fully supported chambers!
👍🤠
Are g20 sf supported chambers ?
Good info on 10mm pistols , thinking of getting one . In A 1911 version , keep the videos coming .
👍🤠
Had a S&W 1006, back early 90's first gun I bought for myself. She was awesome. I now own a Glock Model 40, shoots ok, not as good as my old 1006, but still a nice pistol.
I hear ya!
My 20 has been by my side for almost 20 years. I don't want to under sale it by saying I love it. But It's an extension of myself. That is an awesome group of pistols you have there sir
Thanks Papa Bear.
I have a glock 20 for the woods, and I carry a range officer elite for ccw. Love 10mm!!!!!!
Yeah buddy!
You do love your 10MMs don't you. As always, a great informative vidio. Stay safe, and keep pumping out the vidios.
Thanks, will do!
Great video as always!
I appreciate that.
I love my RIA Tac II in 10mm. I couldn't believe how well it shot. Especially for what I paid for it. Just an all around great shooter. 10mm in general has always been one of my favorite cartridges. Just an all around great round. Definitely can get some work out of it.
👍🤠
Same here... Rock Ultra Tactical FS II in 10mm... a real tack driver, flawless and a joy to shoot. Due to how satisfied I was with that Ultra 10mm I've actually bought two more RIA 1911s: Rock Ultra CCO in .45ACP and a Rock Ultra FS Tact II in 9mm, just because. ;)
@@jmichna1 Nice, I have another in .45 and its been an absolute beast. I love it. It's actually never given me an issue. I'm not harping on people who spend thousands on a 1911, but I didn't and I'm not regretting it. It runs great and shoots straight.
I love mine , shoot's great, fits the hand smoothly , only thing I can say that I don't like about it , is the double stack makes it damn heavy, but it is what it is
@@shatterspirit3349 I have medium-sized hands, and that double stack 1911 feel in the hand, well just doesn't fit my hand well and it seems to lose that "1911 feel" I expect... All my 1911s are traditional single stack.
Another top video... Thank you.
My pleasure!
Thanks for the information
My pleasure
Looks like a lot of mighty fine handguns.
I think so.
Excellent! Thanks and Blessings!
Thanks, same you too!
With the palmswells, the Tanfo doesn't slip and dip forward put of my hand. It just sits solidly in my hand now.
Excellent! 👍
Good advice & info
Glad you think so!
Thank you for this!
My pleasure!
Great info I had no idea about. I tend to fact check any new information from any new sources because today there’s just so much wrong and misinformation being spread for political and financial reasons. Every thing you said was 100% bang on. I own a Glock 40 MOS long slide in 10mm. She’s a beast. A bit much for concealed carry but I do anyways because of the power and reliability. A thousand rounds and never a malfunction. I will be back having subbed and liked. I will check all your other videos out as well. Thank the RUclips algorithm for bringing us together! Lol
Thanks - and welcome aboard.
great vids , thanks.
Thanks for watching!
Thanks for making this video...👍😎🇺🇸🇺🇸🇺🇸.
I have tried to explain this very subject to some die hard Glock fans.
The whole idea of shooting reloads in an unsupported glock barrel is a catastrophic dangerous accident waiting to happen.
I have seen first-hand-hand of glocks blowing out the side of the grip and injuring the hand...there are actually some Utube videos showing this as well.
I had Glock fans call me all kinds of glock hating names because of my attempt to advise them of this problem but that's ok,im a no body...But Now maybe they will respect your input,advisement and except this very fact before they have this failure👍.
I have a video uploaded that explains this issue in more detail. Have them watch this one: ruclips.net/video/SqDLiYOQUwc/видео.html

Thank You👍😎🇺🇸🇺🇸🇺🇸
I gotta 20 and I love it first handgun I bought for my self never had a blow out gen3 but I am now gonna upgrade barrel already did with the 21 thanks for the heads up
My pleasure.
Love watching your 10mm videos . Thank u for keeping on with the videos… Oh and I think if you trade that EAA and sig you can get a Springfield Ronin in 10mm now that is a SEXY 1911 in 10!
👍🤠
Beautiful handguns.
Thank you.
It's well know among 10mm enthusiasts that the Colt Delta Elite didn't have the case support at the 6 o'clock position. There are small barrel makers who make and fit fully support barrels into Delta Elites $$. With that being said, it was the Delta Elite and Glock 20 that kept the 10mm auto on life support. And Double Tap brought back the full power loads along with other small ammunition loaders. When I got my Glock 29 there was very limited selection in 10mm handguns/manufacturers, friends and others tried to talk me out getting it because they thought it was an obsolete caliber.
In the last few years, the 10mm round has started to become more popular. A whole new generation has finally discovered it - and I personally think that's cool.
Thanks for the info.
Any time!
I had to sell of my 629 when I got laid off because of quarantine. To make things worse, I went back to work two days after. I treated myself to a gen 4 glock 20, since I wanted a new woods gun. Don't get me wrong, I love 44 and 357, but 10mm is probably the most fun to shoot, even in the glock. Just went and picked up my second 10mm, I got the ronin 1911 in 10mm, can't wait to shoot it. Sure I will love it. That sig p220 in 10 is next on my list, if I ever find one
I have a Glock 40 Longslide with the Alpha Wolf barrel and Carver Comp on it. I love it.
👍🤠
Loved that pistol display.
👍🤠
The 1911 Colt 10mm is a gift from the Gods!
👍🤠
You are singing my 10mm song! I have been watching your vids for 3 years now. Be advised, when I saw your video pop up today, I noticed I had been unsubscribed from your channel. I did nt do that, RUclips did. Just fyi.
They've done that to me as well - no clue why.
Excellent info Sir
Thanks Cobra!
Love this channel
Thanks Jim.
Good, valid info here, liked and shared
Thanks for sharing!
I still love my mid-late '80s Delta Elite, but I do baby it a bit these days. I've had instances with bulged cases, but no ruptures thankfully. This is especially true with the hotter factory loads, but never an issue with my reloads.
Wow that's a rare kitty hold onto it and baby it and love it I darn would I had a airsoft delta elite in 2001 lol I was but a lad and I fell head over heels for the 1911 only thing I don't like os the safety lever like if you don't train to flick it off you have that pause and I got drilled a ton by my brothers and when I got my p99 it stopped and I got some payback lol also that p99 was co2 powered and like shot plastic bbs but wasn't an airsoft one at all but the delta was such a well made thing I got to hold and ogle one in florida but I shot a 1911 in .50gi as the dude had one on hand to hire also had a go on a mp10 basically a mp5 in 10mm that thing rocked
👍🤠
Great narration.
Thank you.
Love my g29. Carry daily. Absolute blast to shoot.
👍🤠
I got the 10mm bug from you. I have a Dan Wesson RZ and Bruin, Iver Johnson Eagle XL. Also like your taste in grips your wife's too. Love your channel.
Thanks, appreciate the feedback!
Thanks again for helping us Best millimeter fans spread the gospel 🙏! For me though, I don't plan on owning a Gluck nor polymer Tanfo.....my modest 10mm collection is: Fusion Combat Commander, SR1911, RIA FS HC, Kimber Stainless Target, TRP Longslide RMR....All ramped and supported
Excellent!
You should really consider the Witness Match and Stock II in 10mm. I have both, and while I love my Fusion, RIA 10mm 1911's, the single action EAA Match with 15 rounds is great. Double action Stock II is also superb. I am a steel frame guy as far as 10mm is concerned.
@@scbane yes Sir I agree
I've been researching the Tanfo 10mm's because of reports about cracked frames, premature deterioration and reliability issues. I know iCarry has been completely satisfied.........
EAA Tanfoglio has several da/sa pistols in 10mm. I’ve had the Kimber 1911, and sold it. I have the Glock 20 and 40. What these have going for them, is 15 round magazines. Accuracy suffers with the Glock trigger. The standard sights suck. The Tanfoglio P Match Pro has better sights, is da/sa and a match trigger. Also has a 15 round magazine. It sells for about the same as the Glocks. The Tanfoglio Hunter is an awesome 10mm. Adjustable sights and a great trigger gives it stellar accuracy.
👍🤠
Good information

Great information!👍🏾😀❤️🇺🇸
Glad you think so!
Good video, thanks

I would have given anything in Vietnam to have had my r.i.10mm .super accurate. To AS far as I'm able to hold on target .bought my ruger revolver in 10mm and it's very accurate. With all weight bullets. Thank you for info
My pleasure George!
I have a Delta Elite/Gold Cup National Match(NOT A TYPO), and have never had an issue with both factory and reload ammunition!
Some people do, some don't - but the potential is there.
