The Agency Mag Ext G17 +5 Ronin Red is a purpose-built magazine extension designed to increase capacity on Glock 17 platforms. Built by Agency Arms—a name trusted in competition and duty holster design—this extension adds five rounds to your standard G17 mag, giving you more rounds downrange without changing your carry footprint. Whether you're running a duty rig, competing on the range, or training hard, extra capacity in a compact form factor keeps you in the fight longer.
Magazine extensions live at the intersection of practical shooting and everyday carry. A +5 extension walks that line well: it boosts your round count meaningfully without turning your mag into a stick that prints like a small flashlight. The Ronin Red finish sets this apart visually and resists wear during training cycles and regular use. Agency Arms' reputation in the tactical community means this piece is built to function reliably through thousands of rounds.
If you're running a Glock 17 duty gun, competition pistol, or home-defense setup, a quality mag extension is one of the easiest upgrades to add real capacity. Pair it with a good holster and belt, and you've made a meaningful upgrade to your readiness.
Yes, the Agency Mag Ext G17 +5 is designed to fit Glock 17 platform magazines.
The +5 designation means this extension adds five additional rounds to your standard Glock 17 magazine capacity.
The Ronin Red finish is applied by Agency Arms to withstand regular handling, training, and field use without premature wear.
