Purchased a JM 625 for my 45th birthday. What a great gun. Very, very accurate. Found some 45 auto rim ammo at a gun shop, PMC 200 grain swc-fmj for 25 dollars a box for fifty. My question is about the Rimz polymer moonclips. How well do they work? Not going to use them for competition, just informal target shooting. Let's hear your opinions. Thanks, bodyguard.
