Safariland Model 6378 ALS Paddle Holster, Plain Black, Fits Glock 19/23 with 4" Barrel, Left Handed

The Safariland Model 6378 ALS Paddle Holster in plain black is a left-handed carry option built for shooters who want their Glock 19, 23, or 32 (4" barrel) secured and ready. The Model 6378 combines Safariland's proven Automatic Locking System—trusted by law enforcement for decades—with a slim, injection-molded paddle design that sits close to the body. The forward weapon cant and compact profile make it practical for both duty and concealed carry without sacrificing the active retention and draw speed serious shooters demand.

Once your pistol is holstered, the ALS locks it in place automatically, giving you confidence that your firearm won't shift or come loose during movement or physical activity. To draw, simply deactivate the lock with your thumb as you obtain your shooting grip—one intuitive motion, no extra steps. The suede lining protects your gun's sights and finish from wear, while the SafariLaminate structure with wraparound design provides the durability you'd expect from a holster used by professional shooters and armed professionals worldwide.

The Model 6378 ships with a 567BL belt loop sized to fit standard 1.5" to 1.75" belt widths, making it compatible with most duty and casual carry setups. If you're a left-handed shooter looking for a retention holster that balances security with speed and doesn't add bulk, this is a straightforward, no-nonsense choice.
