Glock 17 Magazine Features The Glock 17 factory magazine in Flat Dark Earth is built with a hardened steel insert encased in high tech polymer the same construction used across Glock s factory magazine lineup to protect against deformation from drops or rough handling. Being a factory original drop free design this magazine is manufactured to the exact tolerances the Glock 17 requires for consistent reliable feeding. The Flat Dark Earth finish gives shooters an alternative to the standard black magazine whether matching a similarly finished pistol or simply preferring the look. As with all Glock magazines a short break in period is recommended loading it to one round short of capacity and letting it sit for a few days to compress the spring before running it at full capacity. For Glock 17 owners who want a genuine factory spare in Flat Dark Earth this 17 round magazine is available for sale at GrabAGun.
