I got mine a few days ago and I'm just now getting around to really checking it out. I field stripped it and while putting it back together, I noticed that the o-ring on the firing pin retaining pin is bunching up and coming out of the hole. I assume this is no big deal and the o-ring is just to help keep it in place, not actually seal anything. Am I on base with this, does anyone else have the same issue with theirs? I also want to know if the pin is recessed enough, it's not entirely flush and I don't want to beat it in. The pics should be evident of what I'm referring to. Thanks in advance.
