Agency Arms
The Agency Mag Ext P320 +5 Ronin Red is a magazine extension designed for SIG Sauer P320 pistols, adding five rounds to your standard capacity while maintaining the slim profile and ergonomic grip that made the P320 a favorite among competitive shooters, duty carriers, and serious practitioners. Built by Agency Arms—a shop known for no-nonsense upgrades that work—this extension pairs proven reliability with a minimalist aesthetic that doesn't sacrifice function for looks.
If you run a P320 professionally or recreationally, capacity matters. The +5 extension gives you more rounds downrange without forcing you to compromise on ergonomics or reload speed. It's the kind of upgrade that solves a real problem: you get deeper magazine wells, better grip leverage, and additional ammunition in the same footprint as many competitors' solutions. The Ronin Red finish is both practical and distinctive—it resists corrosion in hard use while making your gear unmistakably yours.
Whether you're building a carry gun, setting up for competitive shooting, or running a training rifle, this extension integrates seamlessly with your P320 platform. Agency Arms' reputation rests on products that work in the real world, and this extension carries that same philosophy—straightforward engineering, no marketing hype, just more rounds and the confidence that comes with them.
Yes. This extension is designed specifically for P320 pistols and adds five rounds to your magazine capacity.
