I just got in from shooting a friend's Tracker. He lent it to me before Christmas, but this is the first time I have been able to work with it. I liked everything about the Tracker, but the clips. Only one would hold the rounds well enough to keep from any coming out before loading the gun. I have a Smith & Wesson that uses full moon clips and they are much more substantial. When my friend first bought the gun, I got out a box of Auto-Rim brass I had left over from a custom loading order some years ago. There was no way to make them fit. Rather than have the cylinder rechambered for .45 Schofield, I would have the breech end faced off, the chambers deepened to handle .45 ACP, and use Auto-Rim cases. That way, it would still be possible to fire .45 ACP, though each cartridge would have to be pushed out with a pencil or something.
