The metal my punch was made from must have been very cheap because the punch actually deformed. Believe me, I beat on that pin but it proved to be a worth adversary. I will have to get a better punch and give it another go. I do think that my problems are ammo related, the primer strikes are solid. The gun shoots fine, hasn't gone full auto on me or anything, but I am very careful with it just in case. When I can get in there and really give it a good cleaning I will feel much better about considering the gun 'battle ready' so to speak.
I like the gun alot. 50 yards from a knee 10/10 shots into center mass, similar results from 100 yards with iron sites, the gun is accurate enough for my current needs/wants.
