I love shooting my Ruger Mark III 22/45.
My only mods are a LCI filler, and a Volquartsen trigger kit.
It is dead on accurate with iron sights at 25', and I love it.
However, I just dread breaking it down to clean it.
Getting the bolt stop pin back in is a real PITA.
I've taken some 00 steel wool to it in hopes of smoothing any bumps out, and liberally greased it up, but no joy!
I was even thinking about trying to find a worn bolt stop pin for it.
It's still fairly new, and I hope that it would get better with time, but at this rate I am more likely to take a hammer to it before that can happen.
Your advice would be appreciated.
