How does that Blackhawk with a 4 5/8" barrel feel when you shoot a full power 45 Colt load out of it? Good God, my 7 1/2" Bisley has crisp recoil with the 12-1300FPS loads with the 300gr XTP-MAG bullet. I would just use your Ruger for hunting, if the trigger quality is what's holding you back and making you want to use the Smith, just get a trigger job. I think the recoil would have to be immense with the full power loads in that short of a Blackhawk. When I shoot the same loads in my short Blackhawk that I use in the Bisley, both .41's, the difference is night and day. Pleasant to shoot in the Bisley, and viscious in the short Blackhawk, and the 45 Colt +P+ loads would be unimaginable.
