I've heard 11 degrees is good, but this was always referring to rifles. My 9mm pistol has what looks to be a 45 degree crown, but a .45acp pistol I have has what looks like a flat crown, and then there is the nicely rounded crown of a S&W revolver. I plan to chop the barrel of a .22 pistol I will be recieving shortly so I would like to know.
