I've put 200 rounds thru my PT140, no malfunctions at all. Gun loosened up after about 150 rounds and works well. It kicks a little heavy and wonder if anyone makes a metal guide rod to help with the recoil? My problem is that is the left rear corner of the polymer frame, right above my rt thumb joint bumps and causes a small blister. Since its a keeper I was thinking a little file work might relieve that little sore that doesn't heal when I shoot the PT140. If I could just trim a little off the frame on that corner I don't think I would have to wear gloves to practice. When I carry, it really doesn't matter as I won't be firing it much (I hope).
