Glock G43 9mm 6 Round Magazine with Extension   #MF08855

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. 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.

These are factory original Glock magazines.  6 Round with Blue Finish.
