I had a cousin, now recently deceased, who spent over 30 years on the bench as a judge in Ohio. He always carried a 9mm Beretta 951 (which I assume is the same as or very similar to the 1951) under his robe, and often outside the courtroom. I don't believe he ever needed to use it, but he practiced with it frequently on the local Sheriff's range, and I went with him several times. As I remember, he really wasn't much of a gun guy, and had no other guns but that Beretta.
