Hi guys, I went to the range today and put about 30 or 40 rounds through my Luger. It was standard Federal 9mm Luger ammo.
I started to notice the metal at the top of the breech block started bulgeing from the keeper steps of the extractor:
What is causing this? Is it a headspace problem? Because I know I am about at the max headspace (.776)
Thanks for your help.
