Glock Glock 27 .40 S&W 10 Round Pistol Magazine Black 10. Standard magazines can also be used for backup weapons. Compact and subcompact GLOCK pistol model magazines can be loaded with a convincing number of rounds i.e. GLOCK 26: up to 33 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.
