I recently purchased a used PT145 and on the initial time I shot it I experienced at least 12 or more failures in the 139 rounds fired. Almost all where failures to feed that had not even started to move the round forward, the slide was in the rearward position. On a few of the failures the slide closed all the way on an empty chamber with rounds still in the mag. The salesman who is also an armorer roughly guessed from the wear on the internal parts that the gun had been fired between 150-200 times before I shot it. I called Taurus and they said I could either send them the gun and mags or just the mags and they will exchange the mags for me. Also the salesman/armorer said he could test shoot it for me and try to determine and fix the problem for free. Should I; 1.Send gun and mags to Taurus? 2.Send only the mags to Taurus? 3.Let the salesman/armorer try and fix it? 4.Any other suggestions? Thanks in advance for your reply.
