I wouldn't be concerned about minor cosmetic blemishes. If the price is right pick it up. I just bought one (too hot and humid to shoot) but I think I'm going to like it. My only concern is that the grips seem awfully thin and I may replace them if things do not go well at the range.
Any gun that is shot will get some wear so dont be too worried about it. PC guns are ment to be used so dont make it a safe queen. I have a PC66 F Comp that I dearly love to shot so buy it and enjoy it.
May not be safe, the scratch could cut you and cause massive bleeding or transmit a disease. I would force myself to help you out by taking it off your hands and sacrifice my health and or blood loss it using this firearm.
I am not trying to throw a bucet of water onto this birthday cake---I promise--however/but--am I the only one that does not like the looks of the PC ?
