When I got this one they also had the .357 version also. I really didn’t consider getting it. However after a little thought, it might not have been a bad choice. A .357 125 grain JHP or JSP pushed with 21 or so grains of 296/H110 could be a deadly deer or hog load. Maybe even with better accuracy than the .44.
I can’t think of any reason that .38’s wouldn’t shoot OK too, if they feed. The limiting factor is the magazine. The cartridges can’t be too long, or too short to get reliable feeding, also it’s a bit picky with semi-wad cutter shapes.
