Promag Sig P320 Pro Sig25 Mag 9Mm 10Rd Blue Steel
The Promag Sig P320 Pro Sig25 magazine is a 10-round 9mm steel magazine built for Sig Sauer P320 shooters who need a reliable spare or duty mag. Whether you're stocking up for the range, competition, or defensive carry, this blue steel magazine offers straightforward functionality and the durability you'd expect from a steel-bodied design. ProMag magazines are a practical choice for shooters looking to expand their magazine inventory without premium pricing.
The 10-round capacity makes this magazine well-suited for states with magazine restrictions, and the blue finish on the steel body provides a classic look while resisting corrosion under normal use. Like all magazines, having spares—especially ones broken in and proven reliable with your specific firearm—eliminates the guess-work during range sessions or when you need to keep your P320 topped off.
Magazine selection often comes down to reliability and fit. This Sig25 magazine is engineered to function with Sig Sauer P320 platforms, so compatibility is straightforward. Run a few rounds through it at the range to confirm feeding before relying on it for anything critical, and rotate your magazines in regular use to keep them in good working order.
