What holsters are available for the Glock 40 10mm?

Alien Gear offers IWB, OWB, and duty holsters designed for the Glock 40's long slide and 10mm frame. Options include the Rapid Force duty holster, Cloak series, and ShapeShift system—each tailored for specific carry needs like range use, concealed carry, or tactical operations.

Is the Glock 40 suitable for concealed carry with an IWB holster?

Due to its large frame and extended slide, the Glock 40 is more commonly used for OWB or chest carry, especially in hunting or outdoor defense roles. However, with a proper IWB holster like the Cloak Tuck 3.5, concealed carry is possible for those who prioritize 10mm firepower.

What is the best OWB holster for Glock 40 outdoor or field carry?

The Rapid Force Level 2 or Level 3 OWB holster is ideal for open carry, backcountry defense, or duty use. It offers active retention, a rugged polymer build, and optional leg strap compatibility for extra support.

Can I use a Glock 40 holster with a chest rig or drop leg system?

Yes. Holsters like the Rapid Force can integrate with MOLLE, belt slide, or drop leg platforms, giving backcountry users and tactical carriers flexible mounting options.

How do Alien Gear holsters manage the Glock 40’s size and recoil?

Each Glock 40 holster is designed with rigid shell support, adjustable retention, and ergonomic backing materials that distribute weight and stabilize the firearm, especially useful for managing 10mm recoil.

Are left-handed holsters available for the Glock 40?

Yes. All Glock 40 holsters from Alien Gear are available in left-hand draw configurations. You can select your draw preference during product customization.

What retention levels are available for Glock 40 holsters?

Level 1 passive retention is standard, but Level 2 and Level 3 retention systems are available in Rapid Force models for Glock 40. These include thumb swipe and ejection port lock mechanisms for secure carry under active conditions.

What makes Alien Gear Glock 40 holsters stand out from universal holsters?

Alien Gear Glock 40 holsters are molded specifically for the slide length, width, and barrel profile of the Glock 40. Unlike universal fits, these holsters offer custom retention, enhanced comfort, and compatibility with accessories like lights and optics—ensuring a confident draw every time.
