any other handgun, EASILLY. It can be a dozen calibers, a pocket gun, a 308 single shot, a muzzleloader, a carbine, more powerful than a .44 (ie, 460 Rowland) shoot low cost 9x19 ammo, etc, In .38 Casull, with the Cylinder and Slide funny-safety deal, and the shortest slide and butt, I'd be tempted to try it, with large pockets. You can get the wt down to 25 ozs, loaded, which is 2 ozs less than today's Dick special .38 snub, loaded with 158 gr ammo. With some sort of stiffener in the pockets, might be ok. It's only 4 ozs more than the Star, loaded. 60 grs at 2300 fps is 700 ft lbs. Pretty mean for a pocket pistol.
