The innovative polymer frame of the GLOCK pistol 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 extremely 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 (Except for slim/slimline models). High capacity magazines are also compatible within the same caliber (Except for slim/slimline models).
