View Full Version : trigger pull mod 90/31
I am new to these rifles and this has probably been discussed already, but...
Anyone care to educate a newbe on what can be done to improve the trigger pull?
Also, are sniper bolts commonly available? They are my idea of improving bolt lift after firing. Otherwise, with the short bolt handle I find that I have to slap the handle to open it.
Any info for the above will be greatly appreciated.
Depends on how much you want to spend. Here is a company that sells a replacement trigger. http://www.huberconcepts.com/Mosin-Nagant_Trigger_Replacement.htm As far as the bolt goes changing out the bolt could cause head space problems. You could cut and weld on a replacement bolt handle but all of this will cost more than you probably gave fore the rifle. The real cure for the trigger is practice and learning how to control the two stage trigger. We become used to our hunting rifles myself included and their trigger pull and any military rifle trigger will be a lot heaver hope this helps.
I see what you mean about the cost. Those triggers are PRICEY!
Thanks for the info.

there is easy fixes for the trigger pull. look at the mosin nets and they will tell u how
well, the easy fix for the triggers is not so easy.
the fulcrum point inside the trigger is and always will be rough,
the catch on the bolt is a issue
the sear/spring combo is a issue
i have spent many many hours with a wet stone and worked on the bolt piece, i made it as square and true as one can, the flat portion of the sear can also be stoned
However there is no way to polish the inside fulcrum point of the trigger, it will always have creep in it, have seen the posts about shims, but then again there still is the casting surface of the pivot point
the best i have come up with so far is 4 3/4 lbs consistant, but i can feel the rough surface and that will have to stay that way or buy the 88.00 dollar trigger with the nylon bearing in it
heres something you might try, it may work or it may not. here is why im suggesting it. Im a retired pipefitter maint mech. and I used pipe wrenchs and adjustable wrenchs in my work and they were always a pain to adjust cause they would always get dirt and rust in the screw adjuster. so one day I coated that screw nut and the threads it ran on they were slick as silk after that. I coated them with silver anti sieze compound like you use on bolts and nuts. If you do it let me know how it works...........oh yes! hope you dont mind getting some on your hands. cause im sure you will, email@example.com
On the bolt lift deal. Baked on cosmolene in the chamber can cause some of the problem, polishing the chamber with a big brass brush can help with that. Tight headspace has been mentioned as a suspect to.
On the trigger, I have found the trigger pulls on these rifles to vary a lot from atrocious to really not bad. That part is pretty much luck of the draw. My 1946 manufactured Soviet M44 carbine has a nice trigger. The bolt on this rifle can be sticky to open after firing with steel case ammo but for some reason brass cased ammo feeds, extracts and ejects without a hiccup.

There is a easy fix by shiming the spring ,i used a steel 1/4 inch washer just had to grind it to fit. Look up fixin the moisin trigger pull on the net.
