Description
- Product Type: Low-profile Belt Slide Outside-the-Waistband (OWB) holster featuring the Automatic Locking System (ALS®). A perfect hybrid offering top-tier weapon security paired with low-profile concealability.
- Compatibility: Precision thermal-molded custom fit tailored specifically for full-size Glock 17 (Gen 1–6) pistols, also accommodating Glock 22 and 31 (Gen 1–4) sharing the same frame profile. Strictly designed for non-light-bearing configurations.
- ALS® Automatic Locking System (Level I Retention): Automatically secures the handgun in all directions upon reholstering by latching onto the ejection port. The draw is completely natural and instinctive: once a proper shooting grip is established, the user deactivates the release lever with a simple sweep of the thumb for a quick, straight-up draw.
- Flexible Body Ergonomics: The standout feature of the Model 637 is its soft, flexible backing body that allows the holster to mold directly around the wearer’s waistline. This unique construction makes the holster ride higher and significantly tighter to the hip than traditional rigid plastic holsters, dramatically reducing printing.
- Handedness: Right Hand (RH).
- Material & Finish: Engineered with a rugged SafariLaminate™ outer shell structure to absorb impacts and resist heavy scuffs. Available in a clean, professional Plain Black finish.
- Attachment: Features built-in, low-profile 1.50” (38 mm) belt slide slots that secure the holster tightly against a standard carry belt.
- Tension Adjustment: Includes an integrated tension adjustment device (screw) allowing the user to seamlessly customize and fine-tune the holster’s retention and drag to their personal drawing preference.
