It would have been nice to have a micrometer or vernier caliper handy to measure your "shim". It's important to know how thick a shim you put in, and the effect on the trigger pull of using different thicknesses. I imagine those terminals you used for shim stock DO come in different thicknesses depending on where you get them.
i plan on buying my first mosin tomorrow sense a local chain store has them for only 120 and i want to get it ready for hunting season thanks for your videos
I could never figure out why my 1921 had such a nice trigger compared to my other three 91-30's until I took them apart side by side and found somebody had bent the spring on the 1921. It does the same thing as the shim, but not wanting to bend the spring on the others I did the shims and it makes a world of difference.
2 pounds is a lot. I have always wanted one but keep putting it off. I shot mgonza's yesterday and loved it. There a lot of fun to shoot! Great video too! I'm all over this. I enjoy tearing things down and doing stuff like this. I work with aluminum all day. I run a cnc machine and have access to vertical and horizontal mills. I'm going to play around with it and see how it goes.
I guess I should really count my blessings. I have a 1945 Izhevsk M44 that I have done nothing to and it is less than a 5 lb. trigger. Now, it is possible that a crafty North Vietnamese knew what he was doing since the gun was a trophy gun that my father-in-law brought back in the late 60's.
I picked up my M91/30 for about 40.00 at a pawn shop. It was filthy, but cleaned up rather nicely. Thanks for posting this, I have often wondered about reducing the pull weight, now I know. I also have a M44 that is pristine. I think it may have been refurbished as their are scribe markings on the receiver from a Romanian plant.
@teenprepper96 The surplus ammo will be, but new stuff like Winchester white box if not. The thing is that the Winchester was $1.00 per shot and the surplus is $.12.
did a trigger job to my mosin and got the pull down to around 4.5lbs with no permanent modification besides sanding and polishing the top surface of the sear where trigger rides, polished inside of the trigger where it hits the sear(there is an angle in there if you round the angle get a much smoother pull) then the main trick to a light trigger with a short pull is use a trigger slack spring but put it in the other way so it pushes trigger closer to sear disengagement vs farther away.
Just another interesting aspect of my Mosin. There was a bone fragment along with a piece of lead core wedged in the stock, also someone was keeping count of something because the is 17 notches cut into the top of the buttstock and when I took the stock off there was strip of heavy paper with what we think says “Я кровоточить к Родине” on it.
@@ebomey actually I have another update; I took the rifle to the range using 1986 Russian brass case surplus ammo and scored some groups at about 1/2” MOA at 100 yards. Took the rifle home, took a little more material off the sear and now I have a 1.5 pound trigger with a clean break.
I posted about using a shim under the sear 10 years ago on the High Road. I now did a study with many Mosins and realize the shim reduced engagement , not a good idea. Polishing does no measurable good. The Huber trigger does no good. The winners are; bend the sear or install a Timney.
@ArtisanTony I hear you, I was not going to get one because everybody had one. Between the fun factor and cost per shot, it is one of my favorite guns!
Other then the shim you can also bend the trigger bar .... I ended up removing the shim and bending the bar. i was able to fine tune it better that way.
Of course they vary- that's the whole idea of shimming something, to adjust for variations. I'm just trying to get a feel for the process, which is by nature trial & error. I understand the whole "if your bolt falls out your shim is too thick" idea, but I'm trying to figure out how to tell if you've done any good. Why shim your sear spring in the first place and how do you know if you've got it right? Are you trying to adjust spring tension, or the angle where it meets the cocking piece?
hey ebomey wats up my brother?? I'm thinkin' bout gettin' a Mosin in 2 weeks. And this may be a dumb question but the Mosin's at my local gun store look BRAND NEW and i'm just wondering if like Century Arms makes reproductions or are they all original Russians? I could research it i know but i figured i would just get some friendly advice. Awesome vid brother! I'm getting my Glock 17 tomorrow so there'll be a good ole Smoky Mountain Gun Show review up this weekend check it out!
when you bent the sear spring/ trigger bar did you notice an increase in the tension to unlock the bolt? I've done three trigger jobs down to 3 or so lbs and they all caused the bolt to get tougher to unlock... ended up cutting the firing pin spring which solved the issue, but I don't understand why that occurs
Okay its official we have a gun show coming 29 and the 30th this month I'm going to look for a mosin now but I'll specifically be looking for the Hex barrel!
I tried using a shin to lessen the trigger pressure, but it increased the slack in the trigger. I instead ground the sear( too much to begin with), the sear stop (had to for engagement and made it closer to trigger), and finally the flat inside the trigger. My results: 1/16" trigger slack (no need for a spring), 3/16" trigger pull, and a much lighter trigger pull ( not sure how much yet, waiting on pull scale to come in). Be careful, it is easy to go too far. I did a bump check, Total PASS.
@mrtlsimon A lot of places don't pull them out and sell them for more .... Like my place. Some do. I was just luck that I asked to look at all they had in stock and the Hex was one of them.
I have some actually shim stock and i should be getting my type 53 (chinese carbine variant of 91/30) tomorrow and if the guns in good enough shape to fire this is going to be my first mod on this rifle Thx much for the idea
unfortunately do to the inconsistencies in rifles that would not have mattered because the same shim acted completely different in my other rifle and I guess that would be the same result if I had 10 of them to do.
@frankthebricklayer You just have to look for the deals. My local shop has the 440 count span cans for .17 per round. $79 I have seen it cheaper yet when you buy 880 or more. I can not afford to buy that much at one time, so I stick with the 440 count tins.
You can drop another 2 lbs by reducing the width and thickness of your sear spring by half, just not where it bolts in and where it goes into the trigger (make sure you polish the spring a bunch and get out all of your sanding marks or you'll break the spring) and take a LITTLE BIT off the cocking sear on the bolt. Also you can put a torsion spring in so it pushes forward on the trigger for a decent 2 stage feel. Next mos in I lay hands on I'll post a video, but I don't get them in the shop
A much better safety check after shimming is to put a folded towel on the floor and with the gun cocked, give the butt a good wrap on the towel, as if you dropped it (unloaded, of course). If it releases the trigger, that gun isn’t safe and you shimmed too much.
For the cost of my AR I could have 40 Mosins. They make a great platform for projects like that. Having said that, I have not done anything to this rifle.
Ebomey, Thanks for the thread. In reading the thread some has asked how to obtain a Hex. I just got mine Jan 1 2014 from Cabela's. They were open New Years Day. I went to them about a week ago. They were out of all units, both the Round and the Hex. I asked them when they might get a shipment in? They had no idea. I was being super nice (My objective was to obtain a Hex unit). I asked if I could place a prepaid order, they said no. They said they would be happy to call me when a shipment comes in. I asked them if they would be getting any Hex units in the shipment? They also said they had no idea, but usually they do get some. I left the store with my fingers crossed. LOL. Well they got a shipment in on Jan 1 2014 and they called me. Well I'll tell you I did not waste anytime getting to the store.. lol. Some food for thought, I don't know if all of their stores got a shipment in on the first or not. This store you must ask for the Hex, the round units were out on the floor and not in the gun room. Also the Hex units were not in the gun room on display. I had to go into the gun room and they went into another room (off of the Gun room) to bring some out. They brought out six Hex units, and I made my selection. They were kinda high priced $169.00 (all units including the round units on the sales floor) but I made up my mine I was not leaving with out one. LOL Give Cabela's a try if you really want a Hex unit. If they don't have any see if they would take your name and call you when they get a new shipment in? This store got a total of 60 uint's, 10 were hex. One interesting thing they told me was the units that they get were never issued to the troops. But they could have been used in training. Mine looks really good. They said they have all of their units re-crowned, and I looked down the bore and it was super clean, no pitting or rust. I'm pretty proud of it. Your brother and you have a great idea. I'm going to keep my unit original and this seems to be the way to do it. At least you can convert it back if you want to. Thanks again for the thread. In the next few days I'm going to check my trigger pull, and I have a few thoughts on this process. So far I really like it.
Thank you .. lots of great info! My place does pretty much the same thing. They brought the rifles out and let me go through them to find the one I wanted.
i dont know why people say put the slack spring in to push the trigger towards the muzzle, i did that and still had that long creep. so i messed around and put the spring in the other way, and now when you pull the trigger you have a very short travel and a nice clean break. i will put a video up monday after i go to the range(went last weekend but videos screwed up) will also post my way of doing the trigger on gunboards soon.

Excellent detail on the job, and comparison!
Very nice E! I don't own a Mosin, but I enjoyed anyway. Always nice to see someone do custom work themselves...

Very cool vid!!! I like the way that gun looks...may have to look into getting one!!!

You will enjoy the rifle, no matter what one you get.

Thanks for another "quick" video...especially one on the Mosin :D
Thanks for posting this, bro. I will try it on my Mosin. I dont have a scale, but I'd bet that the pull on mine is close to 10 pounds.
Just another interesting aspect of my Mosin. There was a bone fragment along with a piece of lead core wedged in the stock, also someone was keeping count of something because the is 17 notches cut into the top of the buttstock and when I took the stock off there was strip of heavy paper with what we think says “Я кровоточить к Родине” on it.
I used your washer technique with a belt sander and some polish. I got my trigger down to about 2.5-3.0 pounds. Thanks!
Awesome!

You can either open the bottom of the mag or cycle the action.
They are all over the place .. one of mine was at about 8.5 and I don't even know what the other was at because it went right off the scale.
@ArtisanTony
I hear you, I was not going to get one because everybody had one.
Between the fun factor and cost per shot, it is one of my favorite guns!
@jeggers65
The stuff is awesome!
I have also used it to repair scratched and yellowed headlights on cars.
I don't know about the Mosin, but their AR triggers are awesome.
from reviews i've seen it's a really crisp pull, plus the safety looks much easier to manipulate while wearing gloves
My trigger pull scale came in today. I was amazed at the results... 2.5- 2.8 pound pull. So SWEET!!!!!
Awesome!
I use the same mothers! It works good. good vid brother!
It really helped mine ... Just go slow, if it is to thick the the gun will fire when the bolt it's closed.
3.25 is as light as I have been able to get it to go, anything lighter than that the firing pin comes forward when you close the bolt.
Other then the shim you can also bend the trigger bar .... I ended up removing the shim and bending the bar. i was able to fine tune it better that way.
Of course they vary- that's the whole idea of shimming something, to adjust for variations. I'm just trying to get a feel for the process, which is by nature trial & error.

I may be able to find an un-fired Mosin, but nobody is remaking the rifle.
Congrats on the Glock 17 Brother!

I'll try that as well. Thanks, my friend.
@ebomey I have a Finnish Mosin with a Hex receiver from 1942,you said you would not modify your hex receiver. Why is that/
That is very cool!
I keep meaning to pick up a Nagant. I don't know why I keep procrastinating. They are very affordable firearms.
@mrtlsimon

@Tardisius
All by shimming it?
@frankthebricklayer
You too.
One of my favorite find to shoot!
ya i've seen those, considering going for a timney trigger now
If you have a pair of calipers, could you possible tell us the thickness of the shim?
@1dabirdman
Make sure you don't have a premature negligent discharge!
And all this time I thought James Bond was pretty knowledgeable about guns.
@Pistolmarkify
Your welcome Bro.
They are a great gun for the money!
When the bolt is closed you pull back on the knob at the back of the bolt and turn it.
@tnekkc
I am not using shims... I bent the sear.
Mine is at 3.25 pounds.
My Mosin Started with 12lbs. Now Im down to 2lbs. by using a 1/4" brass washer and trimming 2 coils off the main spring
I have a question, Im getting a mosin soon and I was wondering, is all ammo carrosive to the barral, is there any that isnt?
do you have any issues with surplus ammo? have you seen any problems with it being corrosive?
@OneMansSanctuary
You welcome Bro!
A much better safety check after shimming is to put a folded towel on the floor and with the gun cocked, give the butt a good wrap on the towel, as if you dropped it (unloaded, of course). If it releases the trigger, that gun isn’t safe and you shimmed too much.
@ebomey Thanks,I didn't know how rare they were.I got mine in Walmart in 1993 so of coarse I didn't feel it was rare.
can you actually feel a difference in trigger pull?
Very nice .. Oh I know it can be brought to far.
@Armedlegally If you cannot find a hex at your gun show. Try looking at Buds gun shop online. That is were I bought mine.
For the cost of my AR I could have 40 Mosins. They make a great platform for projects like that. Having said that, I have not done anything to this rifle.
Im just wondering....you have so many great vids....why is it popping up on youtube in 2020 just now? These are great instruction vids...
RUclips does some strange thing!
yea I guess..
@Glockwork9
If you come up with something, I would be interested!
I know I could go a little more safely.
@kysteelworker
I can't believe I went this long without one!
Thanks Bro.
Aren't those electrical contacts aluminum? If they are then "galvanic corrosion"
It's been 3 years and nothing.
Is $119.00 for a hand selected Mosin a good buy?
@TheMultiGunMan
I thought NyQuil was supposed to make you tired!
Did you hand polish or use a rotary tool ?
I don't get it, could you do that again lol?

Both of mine where barley hand tight.
What type of trigger-pull gauge is that?
i dont know why people say put the slack spring in to push the trigger towards the muzzle, i did that and still had that long creep. so i messed around and put the spring in the other way, and now when you pull the trigger you have a very short travel and a nice clean break. i will put a video up monday after i go to the range(went last weekend but videos screwed up) will also post my way of doing the trigger on gunboards soon.
good vid mate!
No I have not ... I will have to look into that!
@mgonza29
Yes they are!
Packs a nice punch.
Just be careful. . If you shim it to much the fireing pin will come forward when you close the bolt.
Yes ... the shim works great. I just decided to bend the sear instead.
Very cool! I'll probably use small slivers of aluminum foil to shim mine up.
@whimberly1
Sure, just for you I installed a special feature called "replay".
Lol
Awesome .. thank you!
