Hello, I’ve been invited to show my soon to be project (inspired by MosinVirus on youtube channel)
I decided to dive in to my Zastava M83 and show some of the rough areas. This being my first revolver, my ambition is to turn it into a nice functioning piece. I’m hoping to get some good suggestions that I can practically incorporate.
Prior to me disassembling the revolver, the trigger pull was hard and felt gritty. Also, the primer strikes were off center, the cylinder stop has some slop in the frame (.008).
Certainly after exposing the innards it confirmed years of pollution was the blame.
After cleaning everything up and further inspection, I did notice that the trigger pin was a bit rough including the bearing surface inside the hammer.
The hammer does not appear to be IMI, appears cut from billet, I’m curious if its worth polishing the rough surfaces out of the hammer pin hole? How does one tell if the factory used case hardening or not, its hard to tell since its blued and the other color is hard to say what it is?
What is the acceptable hammer pin slop? I’m considering getting a set of pin gages (minus) and hopefully start my quest with dialing it in closer than Factory originally had and still maintain functionality
The trigger / hammer pin measure at ~0.157 in dia., holes in trigger / hammer measure at ~0.166. .009 seems big and its visually unappealing with the wobble.
Aftermarket parts are non existent, how does one go about creating a oversized two step pin as shown in the image (jewelers lathe)? Anyone have a different suggestion, sleeve the pin, can those be made in custom sizes?
