Glock Magazine Glock 26,9mm 10-Round GLOCK MAGAZINES Like no other pistol, GLOCK pistols permit almost unrestricted compatibility of the magazines within a caliber. Standard magazines, for instance, can also be used for backup weapons. Compact and subcompact GLOCK pistol model magazines can be loaded with 10 rounds 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 resists deformation – even when dropped from great height or exposed to extreme environment conditions.
