Well, as noted earlier, mine was one of the first samples out of the gate. Later models may have been revised. When you examine the gun (but aren't allowed to disassemble it), lock the slide back, turn it upsidedown, and look at the disconnect notch in the bottom of the slide. The disconnector contacts the notch at the front of the notch's arc under recoil and note any wear or burrs there. Take ahold of the front sight and give it a little pressure left/right to see if it moves. Certainly the more current tilting barreled PTs nowadays likely overcome the problems I saw.
