Open-Top Paddle Holster with ALS Combining the concealable, accessible design of an open-top paddle holster with the security of ALS, the Safariland Model 6378 Holster is made for the rigors of daily use by plain-clothed officers and sidearm carriers. ALS locks the firearm securely in place when holstered, but still allows a natural draw with a swipe of the thumb release as you establish your grip. SafariLaminate construction makes the holster strong on the outside, while SafariSuede on the inside protects your firearms front sight and finish. The Model 6378 comes with both the paddle attachment and a standard belt loop, making this holster as versatile as it is functional.
