I have one. The only reason I got it that I got it really cheap. It is not the finest example of craftmanship I have seen. I had read a lot about them both pro and con, and I was more than a little leary of it. But like I said the price was right. So on my first outing with it, I didn't have very high expectations. It was at a developed police range and I shot it from the 7 and 15 yard line. I also used several types of ammo. I was with a friend and he also shot it. The sights shot to point of aim for both of us. Neither of us had any failures to feed or eject. It ran 100% reliability, that still worries me, after everything I read about it I was expecting something.
The only problem I had with it and a Beretta 70s that I was also shooting was both pistols magazines will allow you to load too many rounds into them. When you've loaded all the rounds that will go into the mag, you've loaded one too many and it won't chamber. Once that little issue was discovered we just made sure to keep a round count of what we charged the mag with, and they ran flawlessly.
So that's one man's experience with one pistol. I'm sure that the folks who have posted problems, had problems and I'm lucky, so far at least. I've also heard/read just as many complaints about the Berretta twin of the PT-22 and they cost twice as much. The bottom line for me is, it's a Taurus and your shooting the dice whenever you buy one, you could get lucky or unlucky. I wouldn't do it again unless it was a great deal. I've only had to deal with Taurus customer service once and calling that experience poor is a compliment.
