The innovative polymer frame of GLOCK pistols does not require grip shells. As a result, it has considerably more space for the magazine body and enables double-row staggered cartridge configuration. For this reason, GLOCK pistols are superior in firepower to conventional pistol models of the same size.
GLOCK magazines have a stiff metal tube encased in the proven GLOCK high-tech polymer. This prevents deformation, even when dropped from great height or exposed to extreme environments.
Magazines are compatible within the same caliber and allow greater versatility. Magazines of the standard sidearm can also be used for backup weapons of the same caliber*. High capacity magazines are also compatible within the same caliber*.
*Except for slim/slimline models
Higher capacity with extended floor plate
The extended floor plate adds up to 2 rounds and gives better control and comfort due to additional gripping surface. Magazines with extended floor plates are available in calibers 9 mm Luger, 40 S&W, 380 Auto and 357 SIG.
Better grip with extended floor plate
The extension for the GLOCK models G42 and G43 adds grip length but does not alter the capacity of the magazine.
