I haven't heard of that particular gun. Specs?You could always looke at the Taurus Ply22 its cheaper than the pt22.
i have the NAA pug and absolutely love it. its a fun little gun to shoot.I've got an NAA with .22 lr and .22 mag cylinders. I keep it loaded with the .22 mags. I love it. I have shot it at the range with the .22 mags and it's just fine. Looks classy, imho, as well.
I have a p 64 that I pocket carry sometimes now, I was looking for something for my weak hand side to use as a backup. I was thinking a small .22, very light recoil so as to be manageable for my left, and loaded with stingers it should be enough of a punch to work.
