Found a 28-2 in the local pawn shop and need some input. It appears to be a satin stainless 4" marked highway patrolman. The finish is what concernes me. It has a good bit of rust specks on it. Is this the proper finish on this gun? how would one get the specks off of it? I can't tell if there is any pitting, looks like surface rust. the grips are of different shades and appear to have been revarnished. Asking price is 299. might get it for less. Good buy or walk on by? If purchased I might use it in USPSA for fun, mostly fun gun, I like the way it feels in hand. Help!!!
