Last fall I purchased a redhawk 45 colt/auto from Longhunter here on the forum. When I was in the LGS to pick it up they had a used GP100 in 22lr that also went home with me. I haven't done anything since then. I'm finding them both a lot of fun to shoot. The 45 is much nicer with hot colt loads since I put a Hogue grip on it last month. In my limited shooting it is grouping quite nice.
