TL;DR - My type 38 firing pin is too thick, should I ground it down? To what diameter?
I have a type 38 arisaka long rifle. After drying firing the bolt is very hard to lift. I believe it's because the firing pin is oversized for the firing pin hole. When the rifle is dry fired, it's basically jamming the firing pin into the hole.
You can see firing pin would not drop free to the bottom of the fired position in this picture:
The firing pin miced out to 0.0765", while my other t38's pin measures 0.069". When I swap in the 0.069" firing pin the rifle dry fires without any problem.
The previous owner said he test fired the rifle and did not experience hard bolt lift after firing a live round. I want to get an opinion on this, should I accept it as is, or chuck it in a drill and sand it down to 0.069"?
Anyway here's a picture of two t38s side to side just for gigs:
