The .38 Super is more popular in South America than
it is here. I see them every now and then, ammo is pricey.
The last ones I encountered were a Taurus and a "frankensteined" Colt 1911. The guy selling the Colt
was trying to get $800 for it.
The cartridge was pretty popular back in the 80's and 90's as a pin gun. I saw alot of them built up on 1911 frames. Better controlling muzzle flip and it would shed some time off your pin time. Was also popular with early "Bianchi Style" shooters. Tom.
