Recently received a blue label G19 from 2009. Unfired (besides factory), no wear on any of the metal or the frame. Head to toe it looks brand new unused except for the below shiney spots on the trigger frame. I was thinking retention holster wear, but to make those marks it would have to have been in and out of a holster quite a bit. The rest of the gun does not say "I was carried". Any opinions would be appreciated. I doubt it came from the factory like that.
