I shoot twice a month in falling plates competition, and use a 1911, and a S&W 625 in .45ACP. This greatly simplifies my handloading, as I shoot the same load in both guns. A friend shoots .40 S&W, and was wondering if one of the Smith revolvers in 10mm will also handle .40, as I believe it fires using moon clips. I told him if the gun uses moon clips, I can't see a problem. Any input? Thanks.
