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.
