The newly patented XGRIP GL19-23 adapts the Glock G17, G22 or G31 full size hi-capacity magazines for use in the GLOCK G19, G23 or G32 compact pistols, incorporating the larger magazine into the grip and increasing the pistol's capacity. Law enforcement and military personnel can carry the Glock G19, G23 or G32 with a standard magazine when concealment is important, then insert the full size high capacity magazine with XGrip GL19,G23 or G32 when maximum firepower and capacity become critical.
