Why Glock 23 Holsters Need to Match Your Gun, Gen, and Gear

Glock 23 Gen 5 Holster Fitment: Precision Beats "One-Size-Fits-All"

Each generation of the Glock 23—especially Gen 5—introduces subtle but critical changes in slide beveling, ambidextrous controls, and frame dimensions. Generic holsters fail to account for these updates, often causing improper retention, unsafe reholstering, or excessive slide drag. Purpose-built Glock 23 Gen 5 holsters eliminate these risks with exact molding, ensuring secure fit and rapid deployment under stress.

Glock 23 Holster IWB: Concealed Comfort Without the Print

The Glock 23’s compact frame makes it a top choice for EDC, but bulkier holsters often lead to printing or discomfort—especially in appendix or strong-side IWB carry. Alien Gear’s Glock 23 IWB holsters offer adjustable cant and ride height, breathable backers, and precision-molded shells that hug your frame and vanish under clothing—so you stay ready without drawing attention.

Glock 23 Gen 5 OWB Holster: Security for Duty or Range

For open carry, a secure draw matters just as much as quick access. Our Glock 23 OWB holsters integrate Level II and III retention with paddle, belt-slide, or drop-leg platforms. These aren’t just shells—they’re tools built to retain your firearm during movement, crowd interaction, or sudden engagements without compromising speed or trigger protection.

Glock 23 MOS Holster Compatibility: Optics-Ready, No Guesswork

If you run a Glock 23 Gen 4 MOS, standard holsters won't clear your red dot or co-witness setup. Our holsters are cut for optics, including clearance for RMR, Holosun, or agency-issued reflex sights. Every detail—from sweat guard height to optic hood spacing—is engineered to ensure nothing snags during the draw or forces a compromise in your carry setup.

Concealed Carry Holster for Glock 23: Form Meets Function

Glock 23 concealed carry holsters must do two jobs: remain invisible and be instantly accessible. Alien Gear’s Low-Pro IWB and appendix rigs combine ride depth adjustability with concealment claws to tuck the grip into your body. That means less printing, more comfort, and zero excuses when it’s time to draw.

Best Holster for Glock 23 Gen 5: Built Around Real Carry

No gimmicks. No soft nylon. The best holster for Glock 23 Gen 5 balances retention, modularity, and wearability. Whether you carry with a TLR-7A, run a MOS plate, or swap barrels between builds, your holster needs to match. We engineer for mission profiles—whether that’s civilian EDC, private security, or uniformed law enforcement.
