As you may know, we kind of have a thing for the .357 Sig cartridge – as evidenced by some our our previous work including our review on the Glock 32, CorBon .357 Sig DPX ammo, Federal Premium .357 Sig ammo, and a less serious work with Hornady’s Critical Defense .357 Sig ammo tested head-to-head with a big jar of grape jelly. That one worked out pretty well for all involved, except for the grape jelly.
Originally introduced in 1998, the Glock 31 was the first of the Austrian armsmaker’s polymer- framed semi-autos designed for the new .357 SIG cartridge, which was developed in the U.S. by munitions designers Michael Bussard and Alan Newcomb in 1994 as an alternative high-powder cartridge for law enforcement use. Bussard explains, “When American law en- forcement agencies found the 9mm lacking in ballistic performance, this cartridge was conceived by the designers as a quick, easy solution to the problem. While several large law enforcement agencies use this cartridge, it remains something of a police specialty.”
I think we’ve reached a point at which we can safely conclude that gun owners are fairly spoiled. Guns have become so well-made, and are manufactured on such an enormous scale, that it’s hard for consumers to find anything but peripheral, nitpicky faults with the most popular guns on the market today, such as accessory compatibility, slight differences in magazine capacity, finish and detailed aesthetics, etc.
