I had one... it was not the best gun I've ever shot. Totally reliable, but the accuracy was probably the worst of any gun I've every owned including a Hi-Point C9 some years back.
I would look at something else; personally, I won't ever consider buying one again. My Glocks, SIG's, HK's, Rugers etc. are all a little different and take some getting used to when you first pick them up, but they will all shoot very straight out of a vise and then in your hands once you're used to them. The PT140 wouldn't even hold a 6" group at 10 yards out of a vise.
