The newly patented XGRIP GL26-27 adapts the Glock G19, G23 full size magazines for use in the Glock G26 and G27 subcompact pistols, incorporating the larger magazine into the grip and increasing the pistol's capacity. Law enforcement and military personnel can carry the Glock G26 and G27 with a standard magazine when concealment is important, then insert the full size high capacity magazine with XGrip GL26 or G27 when maximum firepower and capacity become critical.
