Beretta 3032 Tomcat

Hey everyone! Long time between post.
Notice several small dimples on the barrel just below the ramp into the barrel?
Are these attempts to harden test the metal? Or some how the firing pin struck there? The last seems impossible.

I don’t remember how to post photos. Yes it’s been a long time.

You could send them to me and I'll post them, check PM. Yes, sounds like it's NOT firing pin. Not down there.
