A cop/detective I know Has never used a holster.
He carries his snub nose 38 revolver in his pants (yes some detectives still carry those down here).
He has an elastic band wrapped around the grip a couple of times to help keep it in place.
He's been a detective for over 20 years and has never shot his own penis.
Incidental... One of our Air Force pilots crashed his jet about 20 years ago.
According the the official Air Force report he blacked out because he mimicked Tom Cruise in "Top Gun" by removing his oxygen mask during a training flight.
Another idiot!
