Agency Mag Ext Glk17 +5 Sage Od
$70.00
The Agency Mag Ext Glock 17 +5 magazine extension in Sage OD is a straightforward upgrade for shooters running Glock 17 platforms who want higher round capacity per magazine. This extension adds five rounds to standard Glock 17 magazines, giving you more rounds downrange before a reload. It's a simple, proven way to extend magazine capacity without swapping platforms or buying entirely new mags—just slide it on and you're running more ammo per reload cycle.
Built by Agency Arms, a shop with deep roots in the tactical and competition community, this extension is made to take the wear of real shooting. The Sage OD finish blends into practical gear setups and handles daily handling without showing every fingerprint. Whether you're at the range, in a training class, or running your Glock 17 as a duty or home defense gun, the extra five rounds can make a real difference in how often you need to reach for a reload.
Installation is quick—no gunsmithing required. The extension simply attaches to your existing Glock 17 magazines. If you're running multiple mags (and you should), adding extensions to several of them gives you a meaningful boost in total round count without a complicated gear overhaul. For shooters who want simplicity, proven reliability, and a no-fuss capacity bump, this is a solid choice.
