I have an opportunity to buy a Sig P225 (not one of the P6 police trade-ins) with a set of Trijicon night sights and 2 magazines. Gun dates to 1987. Seems in very good shape, though there's some wear on the sharp edges of the slide and some holster wear. I've field stripped it and the rails and interior look good. Asking price is $475. Is this a good price?
