I did have a 3rd generation PT145 for a while. The slide was loose and rattly, but it was surprisingly accurate and reliable. I never had any feeding or ejection problems.
I did, however, have one major problem. A very small part in the FCG broke (a small link, about 1/4" long)....and the gun went full auto. Subsequent investigation revealed that the Mill Pro series guns had originally been designed as DAO. For the third generation, Taurus added an auxiliary sear assembly, converting the pistol to SA/DA operation. The part that broke was part of this added sear assembly. I removed the add-on sear assembly, thus converting the pistol back to DAO operation. After that, IMO, it was a much better pistol anyway. Reliability continued as before.
I sold the PT145 a short while later.
