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 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. Magazines with extended floor plates (plus 2 rounds) are available in calibers 9x19, .40, .380 and .357.

The sale of magazines larger than 10 rounds is prohibited in: Cook County,IL; All of CA, All of HI, All of MA, All of NY, All of RI.
