I bought a PT22 in 1998. I had issues on my 1st trip to the range - sent it into Taurus, and got it back - never had another problem with it again - works great.
I wanted a Glocklight for my Glock 34 last fall, so I figured I would sell it - my mother ended up buying it, so for all essential purposes, I can get it back and take it to the range anytime I want to.
It makes a good pocket gun. At the time I bought it, I debated where I should get a 22 or a 25. At the time, someone posted some stats on one of the gun sites, and it seemed that the 22 actually would do more damage (depending on the particular bullet).
While U are not supposed to fire hyper velocity rounds in the gun, I shot a few hundred thru it before I realized that - whenever I carried the gun for self-defense purposes in my pocket, I kept those in the mag (they are hypervelocity hollowpoint rounds) - I figured 2 or 3 more wouldn't matter after I had shot that many initially.
Still, the gun does have a fairly heavy trigger pull, and is essentially more of a mouse gun than a super accurate range gun. Realize that.
I think U'd be better off buying a Beretta Tomcat, however.
