I believe the North Carolina state game wardens were at one time issued the M13. My best friends dad always talks about his M13 and what a death ray it was. He killed a big buck with it while on patrol.
I bought a blue 3" M13 for my then fiancee. When we agreeably went our separate ways, she declined to sell it back to me. It was a fine shooter and balanced beautifully.
About a year later, I consoled myself by buying a 3" M66, so all's well.
