Sir, I own several of the Taurus Trackers in .45acp. Only one works with the auto rim ammo. It was modified and not all can be. I am a Taurus fan, but if you want to use auto rim ammo your gun will probably be a Smith. The
Taurus guns I have with the full moon clips work great. The spacing at the cylinder is too tight on the Trackers for the auto rim to fit. Being 5 instead of 6 shot the hand wants to hit the auto rim rim and screw up the timing if you open the face to allow for the thicker rim.
