Was at my LGS (also a pawn shop) contemplating a Ruger GP100 in Stainless. The lady at the desk said it was "New In Box and had never been fired". However, upon opening the cylinder, I witnessed just a messy black all over the front of the Cylinder. Now, I am new to hanguns, and extremely new to revolvers. She was willing to give a satisfactory deal on it (if it was in fact NIB). My question is, would the few test fires done at the factory make a noticeable build up of black on a new gun, or was she pulling my chain and trying to get rid of used merchandise at new prices?
