.38 Super is (used to be?) fairly popular in Mexico, where 9mm Para and .45 ACP are banned as "military calibers".
Ah, thank you - I was curious. It's a nice caliber, actually, low recoil in the 1911 frame and flat-shooting. Big IPSC caliber because you can make major with it and the muzzle stays on target. My brother built one for me and the dang thing sounds like a cannon. Sweet shooter...
