Not pretty, but it's a simple and solid 6+1 X 9mm.
I was talking with a guy my age (65) who got mugged last month. He wasn’t able to get his pistol out of his pocket in time to ward off the first punch. He was on his knees and grabbed the guys leg, pulled him in close, stuck his tiny Kahr CW45 between the guys legs and fired four rounds straight up. The show was over before the mugger knew what happened.
