Hi all, I am firing an older (’86) Sig 220 .45 and am noticing a strange mark on my spent primers. The best way to describe it is that it looks like the firing pin “drags†across the primer during the ejection process. It looks like a “Q†Does anyone know what causes this? Before I start replacing recoil springs, firing pin springs, etc, only to find out that I just needed to pop some roll pins & give the breach a good cleaning. Thanks in advance for the help ‘cause I KNOW somebody on this board (probably a bunch) have the answer(s)
