A revolver cartridge designed in the 1920s with the .38 as base. At that time it was the only bullet that could penetrate the bulletproof vests of the time. The bullet is 0,357 inch(or just about 9 mm.)wide. It packs a vey nice punch, you feel a bit like
Dirty Harry when you fire it (even though he uses the .44 magnum, which is just about twice as powerful).
Personally, I prefer firing it in one hand - which i do with all revolvers and semi-automatcs. This means I never hit anything XD
It's the most powerfull handgun cartridge you'r allowed to shoot with in Denmark, where I live. I personally own a Smith & Wesson m.27, which is a relatively common piece in this caliber. General
George Patton had the same one. He called it his 'Killing gun'. Obviously he's was a bit more pimped than mine, with mother-of-pearl grips and all that pretty stuff.
