I've never met a parks and wildlife ranger (game warden) what ever they call them in your state that gave a flip for shooting handguns. Carried a bunch, shot a little is what I'm sayin. That's a steal and GB is right. Quit readin them damn gun rags and believe what you see instead.
I have put thousands of rounds thru the Model 19s and 66s and have never even gotten close to washin a barrel out. If you don't like the rear sight, order a black one. Their screw on. Get a smith to dove tail the front sight and put a red, green, or black insert it it, and be the proud owner of a gun I can't seem to locate for myself.
