Safariland 6378 ALS Belt Paddle Holster for Glock 20/21 - Right Hand, SafariLaminate Finish

The Safariland 6378 ALS belt paddle holster for Glock 20/21 is built for shooters who need serious retention without sacrificing draw speed. Whether you're a plainclothes officer, armed professional, or serious civilian carrier, this right-hand holster combines Safariland's proven Automatic Locking System with the clean lines and accessibility of an open-top design. The moment your Glock settles into the holster, the ALS engages automatically—keeping your gun secure and exactly where it should be. A quick thumb swipe on the release lever as you establish your grip gets you on target fast, no fumbling, no hesitation.

The 6378 rides high and close to your body for natural concealment under a jacket or cover garment, and the slight forward cant of the contoured paddle puts your gun in the most intuitive position for a fast, clean draw. SafariLaminate construction on the outside handles the wear and tear of daily carry, while the inner SafariSuede lining protects your firearm's sight and finish from contact damage. Dual attachment options—both a paddle and a standard belt loop—let you adapt this holster to your carry preferences and rig configuration.

If you carry a full-size Glock 20 or 21 and want the balance of security, concealability, and responsive access that professionals depend on, the 6378 delivers. It's the kind of holster that earns its place in your kit through reliability, not marketing.
