Glock 31 handguns in 357 Sig for sale by Omaha Outdoors are among the most rare Glocks available: those chambered in 357 Sig, a cartridge introduced with much fanfare but which has yet to gain much traction in the market. Quietly, though, many law enforcement agencies including the Federal Air Marshals Service and the US Secret Service have adopted 357 Sig for its unique combination of high capacity and high velocity. Out of the 4.48” barrel of a Glock 31, you can expect the 15 rounds held in a standard magazine to travel at speeds sometimes in excess of 1500 feet per second, something no 9mm, 40 S&W, or 45 ACP can hope for. At these velocities, the 357 Sig bullet has a good record of penetrating barriers like car doors and still delivering plenty of hurt on the other side. It also shoots very flat, even out to 100 yards when most pistol bullets start dropping like a rock.
The 357 Sig is often compared to 357 Magnum, a cartridge with a legendary reputation. While the 357 Sig doesn't quite match 357 Mag velocities, it usually has a shorter barrel and it carries almost three times as many bullets. With greater attention paid to developing quality 357 Sig hollowpoints because of its use by federal law enforcement, it's safe to say that 357 Sig is a solid bet and would perform as well or better than most 357 Magnum loads in most situations. We carry the Glock 31 Gen 3 and Glock 31 Gen 4 with both 10 round and 15 round magazines for those in non-free and free states, respectively. G31 Gen 4s feature interchangeable backstraps and a more aggressive grip texture.
