I have a Taurus 9 shot 22lr revolver. Cool little gun. I bought it for the wife and kids to have something to do if they were to join me at the range and not like the "real" guns!

What I use it more for is training . . . I randomly load 3 to 5 rounds and then have the person shoot it and watch for flinching.
I WANT a P22 . . . but haven't picked one up yet. Of course I have a 22 rifle as well. They're all fun and very cheap to shoot.
