As far as I know, it's basically a 1" 58 cal Renegade. Sure looks like it holding mine side by side. I've been told though, that you can't put a double trigger on it. Drat. There are several "versions" around- some with QLA and some without, and some with the tang drilled with three holes and some with two. Mine is an older one with 3 holes, while my son-in-laws has a higher serial # and no QLA. My hunting pard's is even new and has the QLA.
