Taran Tactical's base pad for double stack Glock magazines adds 3 to 4rds depending on caliber - more in 9mm, slightly fewer in 40 S&W. The coyote color marks competition magazines at a glance in a bag full of black, and the added base weight helps empties clear the gun cleanly on reloads.The oversized footprint also gives a positive grab surface for stripping a magazine during malfunction drills. TTI pads swap onto the magazine body in place of the standard floorplate with basic tools, and they have been fixtures on match guns long enough to need no introduction.
