OP, I just bought a 625-8 "Jerry Miculek" 4" barreled version Thursday in anticipation of using it as a woods gun because it can be loaded with .45acp, .45Auto-Rim, and my favorite handgun caliber... 45Super with no modification at all. This has been confirmed by both Smith and Wesson as well as Tim Sundles, the owner/manufacturer of Buffalo Bore ammunition. I just posted pics of mine in the "Revolver" section here and am awaiting friends to go to the range today... later to put up a full report after running .45acp and the .45Super. I looked for a 625-3 for a long time but couldn't find one as the are harder to come by. So I decided I couldn't wait anymore and picked up the 625-8 version. I think it just may become my favorite revolver and possibly my favorite handgun in short order if it's anything like what other's in the know have told me. Post pics!
