The Model 25 in .45 ACP chambering requires half-moon or full-moon clips for reliable extraction since the rimless .45 ACP does not headspace on the cylinder step naturally. The 6.5-inch barrel configuration was the original target and hunting length for the N-frame .45 ACP platform, used in competition and by 1911 shooters who wanted a revolver with compatible ammunition.
