This Glock 17/34 9mm 17rd Gen 5 Factory Magazine has a hardened steel insert and is encased in a high-tech polymer. This polymer coating protects the magazine and prevents deformation, even when dropped from a great height. Glock factory magazines ensure smooth, reliable feeding and help you stay confident that your pistol will perform reliably. This mag features a round count indicator on the rear face of the mag body and the standard factory base plate.
NOTE: All current production Glock magazines are also compatible with all previous generations of Glock pistols. Additionally, while these mags are brand new, they are not in retail packaging because they were purchased in bulk.
