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.
