The Model 610 is a six-shot, double-action revolver chambered for the 10mm Auto cartridge first created for the Bren Ten pistol. It is manufactured by Smith & Wesson. It uses the N-frame, similar to the Smith & Wesson Model 29 in .44 Magnum, and the Model 28 in .357 Magnum. Since the 10mm Auto is a rimless automatic pistol cartridge, moon clips are used to hold cartridges when loading and extracting spent cases en bloc. Since the .40 Smith & Wesson is a shorter, less powerful variant of the 10mm Auto but has the same diameter, the Model 610 can also chamber and fire .40 Smith & Wesson rounds.
