View Full Version : M91/30 firing pin spring service life

02-02-2012, 2:11 PM
So I have a very early CAI m91/30 mosin import. The rifle while very rough and not arsenal refinished is a very good shooter with no counter bore. While I was out shooting the other day someone remarked on the rifle and how rough it looked, which to me just adds character. But it got me thinking, when if ever should I go about replacing the firing pin spring? As I am sure it is likely the original from '44. I don't have a problem with light primer strikes, but I figured it was worth asking.

I recommend buying a spare spring, just in case, but... if it's not broke, don't fix it.

I'm sure you've heard the saying "if it aint broke..."

If it is broke, Wolff springs are very high quality - www.gunsprings.com

Nothing wrong with replacing it, it may improve your shooting since it could decrease lock time, assuming the current spring is weak.

On one of my more worn looking 91/30s' the spring has a curve to it. I haven't fired this one yep but i'm going to pick up some spares anyway.

You are over thinking this!

Sure have an extra spring just in case..........in case of what I do not know!
