Standard OEM magazine for a Glock pistol. Glock magazines feature a two-part construction consisting of a steel inner frame encased in a polymer shell. The combination of polymer and steel allows for unrivaled durability and reliability from both impacts and the elements while ensuring consistent feeding even in the harshest conditions. This model fits a G17 and has a capacity of 17 rounds. It is compatible with Gen5 models only. These magazines were acquired as part of a law enforcement surplus and may show signs of use and wear but are otherwise in perfect working condition.
