Picked up another one of these in 38 special, it's a little large for the smaller cylinder and has small cut outs at the edge of the cylinder to fit the case rims. Parked next to the same revolver in 32-20 which does not require the cut outs, it's available in a variety of barrel lengths. Both revolvers have about the same single action pull as the Colts underneath but not the double action feature which made the Colt version such a seller in it's day. Both shoot well, better than the originals, and use easier to find ammo. They make good lightweight companion guns to those with lever action rifles in the same caliber. It is also offered in 327 magnum.
