The 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. Weather- and temperature-resistant SafariSeven non-marking nylon blend, the Model 7376 7TS will not scratch or mar the finish of your firearm, and its raised interior stand-offs allow dirt and moisture to clear quickly.
