I picked up a nice East German Mak not long ago. Love the gun--very accurate, reliable, compact, well made. Then I noticed something: ejecting a chambered round revealed a nick in the center of the primer. Checked another round I had chambered. Same thing.
I Googled it. Apparently it's a thing: the free-floating firing pin peaks out of the hole when the slide closes. I guess it's not enough force to ignite the round (to be fair, it's much less than a dimple on a fired case). But... damn. Anyone have a lot of experience with Maks? Anything to worry about?
