91/30 trigger job ??

[Jack Stanley]

Does anyone have an online reference for how to clean up a 91/30 trigger ? A few pictures would help greatly .

I've changed trigger parts for a Garand to get better let off and haven't had one double or worse and cleaned up a Marlin bolt action rim fire rifle . With the rifle I have , after a trigger pull about a yard long it catches just before release .

The search function turned up using tooth paste and that was about it .

Thanks , Jack

Try this: http://www.surplusrifle.com/shooting2005/mosinnaganttrigger/index.asp

I'll add that this method puts a lot of takeup slack in the trigger but does lighten the pull a little and as Gtek says check for good lock up.

[Gtek]

If you try that method, also check this out at end for safety check. Close bolt on EMPTY chamber,
cocked. Now lift up on bolt handle, rattle up and down. Mosin's are very loose and while not having a round in will make slightly more clearance, cocking piece will slip over sear if on edge,back off a little. Gtek

And then if you don't mind spending a little money on it, there is always the Jack Huber modified trigger.

If you want a really nice trigger and are willing to spend about what the rifle probably costs to begin with, you could go this route.

Thanks guys ! I thnk I'll look into the shims first , I think I can handle that and see how it works .

Take out the bolt pull the trigger and put a piece of inter tube behind the sear this takes up the slack.

[Jack Stanley]

TreeKiller , let me see if I got this right . Use a small piece of inner tube between the trigger and the bolt stop ? I think I can see this in my head , it stops the trigger from sticking up so far right ?

I would be very cautious using something like rubber. Too likely to change with use and temperature. Probably works fine but at any time it may allow an unsafe condition and the bolt can release from only bumping the stock. What will you be doing when that happens? Rubber has no place for use in trigger systems. There is a Russian text manual that shows pictures of how to change the Mosin Nagant trigger system. You should be able to see clearly what the changes are doing.

There are many ideas to change the Mosin Nagant bouncing around the net but if they are not what these photos show, my opinion is that they are incorrect and possibly compromise safety. The Russians had years to develop these changes and they should be noted as being the "authorized" changes.

Be safe!

I put shims under that "flat spring" and polished a small burr from the face of the sear . Now at least the catch at the very end of a very long pull is gone . I haven't fired it yet but tapping a lead hammer on the side of the reciever didn't shake the sear loose and after putting the wood back on bumping the buttplate hard on the deck out back didn't make the sear release either .

I can see figure A and B are changing the engagement and angle of the sear but picture 28 though ....... would thinning that area be reducing the weight of pull ?

Thanks , Jack

Hey fellas:
I bought one of the Huber triggers about 2-3 years ago. I was expecting great things.
It was and still is very disappointing.
I did look for another/better/more better fix after putting in the Huber.
I went ahead and did the shim thing.
SAFE NOTE: If you shim too much, the rifle CAN/WILL discharge, without your help.
The trigger pull is a little lighter, but the creep is atroshious. Very smooth, but loooooooooog.
One of the biggest problems that I see, (on my m44) is that the bolt can move up and down when it is in battery condition. In other words, one can actually lift up on the saftey and the sear and bolt engagement will actually slide against each other. If you shim too much, you can actually lift the bolt off of the sear engagement and the firing pin WILL fall.

I don't know that I would change the contour of the sear as per figure B, POST #8
unless I had another to install if things did not work correctly.
I would however like to try this and see if it changes the trigger for the better.
I paid 72.00 for the Huber trigger with postage. I would be very interested in the Timney trigger, but I have quite a bit of money in my M44 already.
I would NOT recommend the Huber trigger to anyone.

TMNEY now is making a "FEATHERWEIGHT DELUXE TRIGGER" for the Mosin Nagant. Its street price should be around $ 100.00 or so...

Now ya got me drooooolin.

try the rubber before you knock it and report your findings.

Jack;
in the picture in post 8 the rubber will go between the sear in the trigger and the back of the housing. You can put it in with needle nose pliers. all it dose is tale up the slack in the first stage. I could not get mine to fire after i did this by slamming the but on the ground.

[daengmei]

but the creep is atroshious
Bending the sear spring upward helps reduce creep and could reduce pull.


would thinning that area be reducing the weight of pull ?

Yes, but do not reduce it too much, the sear spring will bend easily or break during use. Do not allow this area to become hot if your using something like a dremel.


I don't know that I would change the contour of the sear as per figure B, POST #8
unless I had another to install if things did not work correctly.


Always have extra and keep the original one as is.



report your findings
You folks do as you please, I won't introduce rubber into the firing system.

[Jack Stanley]

I tried the Rifle out today using the shim method and while the pull was still yards long it was smooth and the "catch" at the end was gone . I think I'll try this a little while longer and see it I can live with it or if it needs more help .
