Glock 31 Specifications

During the 1990s, the .40 S&W cartridge became the choice for law enforcement agencies nationwide, including prestigious agencies such as the Federal Bureau of Investigation (FBI).

Its proponents cited the benefits of increased muzzle energy and projectile mass compared to 9x19mm, without the drawbacks commonly associated with .45 ACP and other large-bore calibers (e.g., low capacity, larger-frame pistols, etc.).

In the gun industry’s search to continue improving the performance of the law enforcement duty pistol, SIG Sauer released an alternative option in 1994, the .357 SIG cartridge. This new caliber is effectively a .40 S&W case necked down to 9mm. Typically loaded with a 125-grain bullet, the performance objective of .357 SIG is to offer .357 Magnum-style performance from a full-size semi-automatic pistol.

One of the first companies to offer a .357 SIG pistol was Glock, with the introduction of the Glock 31. This new polymer-frame pistol was identical in almost every way to the .40-caliber Glock 22, with only one significant difference: the barrel and the corresponding performance.

Even the new Glock magazine was identical to the one in the G22. The only difference is the markings (.357 instead of .40), ensuring the new G31 offered the same 15-round maximum magazine capacity as its .40 counterpart.

Although the G31 didn’t achieve the same success and acceptance with civilians and law enforcement agencies, many local and state organizations still adopted it. Glock 31 adopters include the Mississippi Highway Patrol, the Tennessee Highway Patrol, and police departments in many states, including Ohio, South Carolina, Texas, and West Virginia.

Incognito Venture: The Ideal Choice For Civilian OWB Carry

The Incognito Venture is an outside the waistband holster (OWB) constructed from low-profile Kydex sheets designed for everyday carry.

Each Kydex sheet used in the Venture holster’s construction is 0.08 inches wide, providing the best combination of durability and ease of concealment.

This custom Kydex holster is shaped and contoured to accept the exact dimensions of the Glock 31 pistol, ensuring a safe. Although it comes standard with a 1.5” holster clip for mounting on standard gun belts, we also offer extended 1.75” clips for gun owners wearing larger belt sizes.

Even though the Venture is an outside the waistband holster, its concealment-friendly Kydex construction makes it an ideal dual-purpose holster. Use it to carry your Glock 31 openly (where legal) for maximum comfort, or conceal it under a single layer of cover garments, such as a shirt or a jacket.

The Venture carry holster is designed to minimize printing and offer the best balance of comfort and maximum concealment, even with full-size pistols such as the G31. For additional self-defense capabilities, consider augmenting your Venture with a Kydex magazine pouch made to carry your Glock magazines, such as the MaxFP double magazine carrier.

Incognito Aegis: The Perfect Pistol Holster For Duty Use

Law enforcement officers, security personnel, and other professionals who need to carry a full-size pistol in public settings need a robust, reliable, and highly-secure duty gun holster. These requirements mean a civilian-oriented self-defense holster won’t suffice, opting for an active retention holster instead.

If you are on the market for a holster with active retention features for your duty Glock 31, consider the Incognito Concealment Aegis. This durable and long-lasting holster is a Level 2 retention holster, which offers passive, friction-based retention and one active, togglable weapon retention mechanism.

In this instance, the Incognito Aegis’s retention system is a locking hood mechanism designed to block the rear of the slide. When engaged, the hood helps prevent an assailant from drawing the weapon out of the holster and stealing it from you.
