A friend of mine is looking to purchase one, and I'm curious if anybody has any leads on who may have them at a decent price. Although, it seems like they're just here and there from, appearing sporadically from private owners. Also, when did the Navy coating change to the nitro-carburized hazardous environment finish? Any specific serial numbers to avoid, look for? Surely more questions will follow, but I'm confident in my knowledge of these handguns already. I'd stilllike to hear what all of you have to say.
