Open-Top Paddle Holster with ALS. Combining the discreet, easily accessible design of an open-top paddle holster with the security of ALS, the Safariland Model 6378 Holster is built to withstand the demands of daily use by plainclothes officers and sidearm carriers. ALS securely locks the firearm in place when holstered but still allows for a smooth draw with a quick swipe of the thumb release as you grip your weapon. SafariLaminate construction offers durability on the outside, while SafariSuede on the inside protects your firearm's front sight and finish. The Model 6378 includes both the paddle attachment and a standard belt loop, making this holster as adaptable as it is practical.
