Glock pistols were designed to allow almost any magazine within a caliber to be compatible.  Unlike any other pistol, standard magazines can also be used for backup weapons.  This allows Glock pistol models to use convincing number of rounds, whether the Glock is a compact or subcompact. The Glock pistol features an innovative polymer frame that does not require grip shells.  This allows the Glock to give more space for the magazine body and allows the magazine to have a double-row staggered cartridge.  As a result, Glock pistols are superior in firepower to conventional pistols. To resist destroying the magazine, Glock came out with a stiff metal tube encased in the proven high-tech polymer. This allows the magazine to be dropped without destroying the integrity of the magazine.
