I have a PT1911 (45ACP), a 605 titanium snubby (357 mag), a TCP-738 (380 ACP), and a 4 inch Tracker (45ACP). Many, many rounds through all of them, not one problem. The PT1911 and the Tracker are both very accurate, the 605 and the TCP do what they are supposed to do. If I could find another Tracker in 45ACP, I'd buy it in a heartbeat.
I have other firearms too, and have had no issues with them either.
