There have been several revolvers that use semi cartridges without moon clips, but that sort of negates the sole advantage, which are the moon clips. Interestingly enough, Taurus once showed an I-framed size (the old S&W Regulation Police sized small frame that predated the slightly larger J-frame) in 9mm. Walt Rauch got one of the production protos and found it to be oen of (or maybe the most) accurate snubs he'd ever shot...and Walt has shoot a LOT of snubs...
