I have about 14 or 15 different revolvers that shoot the .45ACP round use mostly the full moonclips for a rapid reload for CCW and have a belt slide with six rounds of .45 Auto Rim for the "last" six. My SAA chambers .45ACP but is not cut for the .45Auto Rim. For that I use as a rimmed case the .45 Cowboy Special which is a ACP case with a .45 Colt rim on it. That works great and also fits in a belt loop pouch. Revolvers are great because you don't have to pickup brass off the ground. I hate bending over. Everything comes out of and back into a nail apron and you can move around without having to use a table. My old Training Counselor Jimmmy Brown ( God rest his soul) turned me on to that. A true gentleman of the old school and one of the best revolver shots I've known.
