I went and got a centerpunch yesterday. Sharpened it a little, and I believe it's working great.
I got tired of loose pins and the slide stop pin was the worst offender. So, I did the bolt thing. It doesn't look too bad but it works very well. The slide always stays back now. This one also has a Harrington HD firing pin/trigger kit also. Next, some nice sights. I have a regular military issue pistol, too. That one only has one modification, a machined firing pin. I'm going to leave that one alone.
