When you need more rounds downrange without breaking your grip, the Sig Sauer 30-round extended magazine for P320, P320 X-FIVE, M17, and P250 full-size pistols delivers serious capacity in 9mm Luger. This is factory Sig Sauer engineering—the same reliability you get from the standard mags that shipped with your gun, but with nearly triple the round count. Whether you're running competition stages, training hard at the range, or building a defensive load-out, having 30 rounds in the mag means you're focused on what matters: your shooting, not reloads.
The design balances practical capacity with usability. A removable polymer sleeve on the base plate keeps the mag comfortable in your hand and balanced in a full-size grip module—you're not stuck with a pinky-dangler feel if you don't want it. The high-lubricity finish keeps rounds feeding reliably through the mag well, and the steel body won't degrade under hard use. Rear witness holes marked in increments of 5 let you count remaining rounds at a glance, which matters in a fight or on a stage. The removable base plate makes field stripping and cleaning straightforward, and the high-tensile spring is built to cycle thousands of rounds without sagging.
Sig Sauer engineered this magazine to function flawlessly with P320 variants, including the X-FIVE competition frame, plus M17 and P250 full-size models in 9mm. If you're serious about your platform, factory magazines mean zero guesswork on compatibility or durability. This is the extended capacity option when you want to shoot longer and reload less.
