The 6378RDS holster is specifically designed for firearms with red dot sights. The holster features the ALS which 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 firearm*s front sight and finish.
