SureFire, LLC's MASTERFIRE™ Rapid Deploy Holster system. The MASTERFIRE™ is a one-of-a-kind retention holster that uses an open top design to securely retain almost any handgun or handgun configuration, including those with suppressors and red dot sights. A proprietary lug-and-cam system locks the weaponlight and handgun in place with Level III retention.
Unlike most holsters, the MASTERFIRE™ is indexed to the WeaponLight, so it can be used with virtually any handgun with a mounted H-Series SureFire WeaponLight. Its unique light-activation switch can be set to automatically activate the H-Series WeaponLight or laser when the gun is drawn, saving valuable time in high-stress situations and making one-handed manipulations easier.
