I just picked up this GP100 today. Bought it on Gunbroker, listed as NIB. It is. All else on this gun is perfect. Save the muzzle. Yes, I know I should have examined the muzzle before I walked out of the gun shop, but I just noticed it. I don't know if any of these are serious, or no big deal. I've only had one revolver before and it was stainless. The scars seem to be on the muzzle, and not on the crown exactly. No, I'm not gonna shoot competition with it, but I want it to be accurate to 25 yds. If these are serious, what can I do? Have it re-crowned? Send it back to Ruger?
