Grey Group Training just added a new holster from Safariland (ALS 6354 OPTIC QLS FORK) designed specifically for Glocks with a slide mounted mini red dot optic or tall target style adjustable sights. It is available in two versions, one is for a pistol with a mounted X300 and the other without, for both the Glock 17/22 and the 34/35 in right or left hand options. The version for the SureFire X300 is specifically designed to interface smoothly with the DG switch. As you can see, the holster is offered in MultiCam and covered in a suede/330D Cordura laminate for sound and visible signature reduction. The Cordura covering and all visible hardware is treated to minimize Near Infrared (NIR) and visible signatures.
The holsters come mounted with a Quick Locking System (QLS) 19 fork and have no other mounting provisions included. However, this will attach directly to a similarly equipped belt mount or leg shroud. The new fork is much stronger than the original model but won’t slide right into PALS webbing. To mount to MOLLE/PALS you will need a MOLLE fork with a QLS receiver. It’s 360 degree adjustable.
One of the coolest things I saw at last week’s
