I recently purchased the same revolver (M19 2 1/2") for cheap. The bluing is in great shape but guess what, it'll be shot, and shot a lot. The difference between a "shooter" and a "collector" is a mere hundred dollars or so. Nothing to sweat. It's not like we're dealing with a $1000 difference.
Shoot it and shoot it again.
