As semi-automatic handguns began to fill the markets, ammunition manufacturer SIG Sauer wanted to replicate the abilities of the .357 magnum, shot from a revolver, in a semi-auto pistol; thus, the birth of the .357 Sig. The Swiss-German firearms company partnered with American company Federal Cartridge to begin producing the round in 1994.
As far as the casing goes, the cartridge for the .357 Sig is basically a 10mm auto case shortened with a neck capable of receiving a 9mm bullet. While the case is a little longer than the .40 S&W, many guns chambered for the .40S&W can be retrofitted for the .357 Sig by replacing the barrel and recoil spring. The first gun actually made for the .357 Sig round, however, was the SIG p229.
With regards to usability, many government and law enforcement agencies have adopted guns chambered in the .357 Sig. In fact, the Texas Department of Public Safety was the first agency to use this round in 1998. Since then, many gun manufacturers have produced pistols that chamber this round, including the Glock 31. Many agencies that have adopted this round allow agents a choice between this and a 9mm. Many, however, still opt for the 9mm solely because the guns tend to be lighter and carry more round
