The firing pin on my brand spankin new P226 has a tiny little defect in the tip.Its a little "crater",one almost needs a magnifier to view it.I noticed it puts a little mark on the primer indents in spent cases,maybe the size of the head of a pin.The piece has been ultra reliable in the 400 rounds or so that it has fired to date.I suppose i should send it back to sigarms,has anyone had any experiencw with the service dept.of sig???Has anyone else heard of bad firing pins in sig pistols? The worst i could say about this one was a few failures to lock the slide back when empty,until i noticed those primer markings!
