RADIAN WEAPONS MAGWELL FOR GLOCK 43X/48A(R) The RadianA(R) ANCHOR + MAGWELL for Glock delivers a rock-solid grip, and effortless reloads. A tapered screw drives the PLANAR-LOK(TM) outward causing barbed teeth to bite into the interior sidewalls of the frame, locking the ANCHOR into place. This patent-pending design eliminates inward wall flex preventing magazine bind, even with large capacity magazines. The MAGWELL dovetails into the ANCHOR at the rear, as it's tooth bites into the front of the frame. The patented ANGLE-LOKA(R) detent drives the MAGWELL rearward into position, completing the system's three-way lock up. Materia Mfg: Radian Weapons
