The Sig Sauer P226 X-Five 20-round extended magazine is built for shooters who demand reliability and capacity in a full-size duty or competition platform. If you're running a P226 X5, MK25, or any 9mm P226 variant and want to maximize your round count without sacrificing dependable feeding, this steel magazine delivers the performance you'd expect from Sig's factory original design. The 20-round capacity gives you significantly more shots downrange between reloads—a real advantage whether you're training hard, competing, or preparing for serious use.
The engineering here is straightforward and proven. A high-quality steel spring and low-friction follower keep rounds stacked and ready to feed without hesitation, round after round. The steel magazine tube is built to last years of hard use, and the silky smooth black finish ensures friction-free insertion and reliable extraction every time you seat a mag. Side witness holes let you glance down and count your remaining rounds without removing the magazine—a practical detail that saves time when you're focused on the target.
Weight savings and ergonomics matter in a high-round-capacity magazine, and Sig addressed both. The aluminum basepad cuts unnecessary weight compared to steel, and the indented front basepad gives your fingers a real purchase when you need to strip a mag fast. This is the kind of thoughtful detail that separates a magazine you actually want to use from one that just sits in a range bag.
