Nagant trigger pull


May 25, 2004, 01:25 PM
Any tips on getting the trigger pull below 10lbs on a Mosin Nagant rifle? It's said the 91/30 sniper rifles had better trigger pulls than the standard models, and I'm searchin' for input on how to get a better pull before I ruin something.

if you install some small washers on the screw that holds the trigger spring to the gun itself you can lower the trigger pull weight quite a bit, but be careful cause you can get way too light, way too fast....

it might not be perfect, but it is damn near free...

I recently got a 91/30, and the trigger was heavy/grinding. When I stripped the rifle for cleaning/lubing, I did some looking at the trigger & sear setup.

Note: I'm not professional gunsmith, just a guy who likes to work on things.
This is what I did; may not be the right thing for you to try, or for your rifle.

There's a slot in the trigger, the sear/spring fits into it. When you pull the trigger, there are three flat angles on the top of the trigger slot that bear on the spring, looks like one is the first stage and one the second, looks like the third is just a relief step.

I used a thin file wrapped with 600 grit wet/dry paper to polish the angles in the trigger slot- do NOT change the angles, just polish!- and used a fine stone to polish the spring surface where the trigger bears. Again, don't take a lot off, just smooth it. Oiled & reassembled, made a huge difference in the trigger action.

Thanks for the tips guys...

I'll tread carefully.....

Kinda been sidetracked, got a Mauser to play with too :)

My M39 Nagant has a crisp 4-6 pound pull on it, just from polishing. Everyone is right when they say tread carefully, if you do decide to polish the trigger CHECK IT OFTEN, you can always polish a little more but you cannot put back what is taken off. My 1891/30 Izzy came to me after "bubba" or one of his friends got to it and polished the trigger so much that the rifle would fire if you dropped it, and the sight hood was sawn in half. The barrel is counterbored and I would be surprised if you hit the broadside of the barn when you shot it inside the barn with the doors closed. I've gotten some 3/4 inch groups from the M39 so there is some life in the old gal, if yours isn't shooting that great either get some sellier and bellot or some winchester or start reloading. I dropped 1/2 inch when I pulled the bullet on some wolf ammo and replaced the powder with some IMR 4350 and put a 147 grain boat tail FMJ on top.

Look at this picture and notice the three layers of masking tape.
Masking tape is .005" per layer.
You can use any tape, paper, or sheet metal, etc to do it.

It reduces the trigger spring force, and it reduces the take up.
It doesn't do anything for the overtravel.

I have been doing some more work, comparing:
1) tape under rear of sear
2) washers under sear
3) Huber aftermarket trigger
4) Timney aftermarket trigger.

I have compiled a mountain of numbers of trigger force data.

The stock Mosin Nagant parts; sear, cocking piece, and trigger can vary enough for the trigger pull to be anywhere from 3 pounds to 12 pounds.

But a very consistent 3 pounds or 12 pounds for what ever combination produces it.

The advantage of the Timney trigger is that the trigger force is not dependent on the Mosin Nagant geometry, and it has a safety.

The disadvantage of the Tinmeny, is that that it costs ~ $100 delivered, and requires some stock in letting cuts.

What I have not done, is work out why there is so much variation in the MN parts.
