The Safariland Model 7378 7TS Holster combines the security of ALS with the speed and simplicity of an open-top design. ALS secures your weapon automatically as it is holstered, yet still allows a fast, natural draw with the swipe of the thumb release as you acquire your shooting grip. Built from durable, weather- and temperature-resistant SafariSeven non-marking nylon blend, the Model 7378 7TS will not scratch or mar the finish of your firearm, and its raised interior stand-offs allow dirt and moisture to clear quickly. Gun fit: Glock 20 Gens 1-4 Glock 21 Gens 1-4
