This is a factory-original replacement magazine from Sig Sauer, engineered to the same exact specifications your pistol originally shipped with. Built from carbon steel with a polymer baseplate, the magazine holds 14 rounds of .40 S&W or .357 SIG ammunition and features a dual-stack design for efficient capacity in a manageable profile.
The precision-engineered feed lips are machined to deliver snag-free performance, and the anti-tilt polymer follower prevents jams and ensures smooth ammunition cycling. The high-tensile music wire spring maintains consistent pressure throughout the magazine's life, whether you're at the range for an extended session or carrying for personal defense. Numbered witness holes drilled along the body let you visually count remaining rounds at a glance without unloading.
The impact-resistant polymer baseplate can be easily removed for field cleaning when you need it, making basic maintenance straightforward. This magazine works exclusively with full-size grip modules for the P250 and P320, delivering a flush fit that doesn't rattle or move in the magwell. The blued finish provides solid corrosion resistance and a low-visibility profile, while the overall construction delivers the durability you'd expect from a firearm as respected as the P320 or P250.
This is a standard full-size magazine and won't fit compact or subcompact grip modules. If you own a P250 in .40 or .357 SIG, this magazine is fully compatible thanks to Sig's proven modularity between the P250 and P320 platforms. For dedicated duty use, range training, or defensive carry, this is a no-nonsense spare or replacement from the factory that handles the job.
This magazine is designed exclusively for full-size models. Compact and subcompact pistols use shorter magazines to maintain proportional fit. While a full-size magazine may physically fit in a compact grip, it will extend below the baseplate. For the proper fit and appearance, use magazines specifically designed for your grip module size.
Yes. This magazine is chambering-agnostic and works reliably with both .40 S&W and .357 SIG ammunition in P250 and P320 pistols. The dimensions and spring tension are optimized for both calibers, so you can safely alternate between them.
Yes, this is a factory OEM replacement magazine manufactured to the exact same specifications and tolerances as the magazines that ship with new Sig Sauer pistols. It uses genuine Sig Sauer components including the steel body, polymer follower, and music wire spring.
The polymer baseplate is easily removable by depressing the retainer and sliding it off, giving you access to the spring and follower. Occasionally wipe down the interior and spring with a lightly oiled cloth and allow components to dry completely before reassembly. The magazine itself requires minimal maintenance if kept reasonably clean.
