The Safariland Solis Holster combines the security of ALS with the release speed and draw simplicity of an open-top design. Solis is compatible with most compact red dot sights and subcompact lights. The ALS secures your firearm 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. The Solis is built from durable weather- and temperature resistant SafariSeven non-marking nylon blend.
