The 357 SIG was introduced in 1994 in a joint venture between Federal Cartridge Company
and Sigarms Company by necking down a 40 Smith &Wesson to .357 caliber or 9mm.
This created a small cartridge equal to 357 Magnum energy levels in a small semi-auto pistol;
however, only the projectile velocity  is better than the 40 Smith & Wesson.
