My first handgun was a PT145, and my second was a PT92. The PT145 has about 4,000 problem free rounds down range, and the PT92 is over 10,000 now. I generally split my carry time about 50/50 between my G19 and my G21, but I still carry the PT145 when I need a small gun for deep concealment. It's actually smaller in every dimension and lighter than my G19 while still carrying 10+1 of 45.
My PT22 is a piece of junk that is usually more hassle than its worth when I do decide to take it out for a little plinking.
