Building on our track record of reliable holster performance, the Epoch Holster delivers three levels of weapon retention for our highest level of security. The patent-pending retention system engages the pistol's ejection port when holstered and won't let go until you release it. As an added safety measure, the Pivot Guard opens by thumb activation and is designed so it won't close accidentally, locking you out of the holster. This unique design accommodates the most popular under-barrel lights on the market today, giving you all the versatility you've come to expect from BLACKHAWK! ;
