This is the factory magazine that ships standard with full-size P320 and P250 pistols. It holds 17 rounds of 9mm and is engineered to work seamlessly across Sig's modular platform, giving you reliable magazine compatibility whether you own one pistol or several.
The magazine features a hardened steel body with reinforced feed lips that won't warp even after extended periods of storage fully loaded. The anti-friction coating keeps everything running smoothly, and the high-tensile steel spring maintains its strength through thousands of cycles. You'll see the same quality control that goes into Sig's firearms themselves.
Numbered witness holes along the side let you count your rounds at a glance without removing the magazine from the gun. The removable baseplate makes cleaning straightforward, and the impact-resistant polymer baseplates provide durability without adding unnecessary weight. The polymer follower promotes smooth feeding through your pistol.
While built for full-size frames, this 17-rounder works across different P320 configurations including the M17 and M18 military variants, and it's fully compatible with full-size P250 pistols. Note that these magazines won't fit the X5 grip module when the extended magwell is installed, but they work with standard full-size and carry-size modules without any issues.
This magazine is designed for full-size P320 and P250 frames. While a 17-round mag will physically seat in a compact or subcompact grip module, it will extend noticeably below the gun, which defeats the purpose of the smaller frame. Sig makes dedicated 15-round magazines for compacts and 12-round magazines for subcompacts that fit flush with those grips.
Sig sources factory magazines from multiple manufacturers and then produces them to their exact specifications. This means slight variations in stamping and finish color can occur between batches, but every magazine meets Sig's performance standards. All are genuine factory magazines, not aftermarket alternatives.
Yes. The P320 and P250 share the same magazine design in 9mm, so a P320 magazine works perfectly in a P250, and vice versa. This cross-compatibility is one of the nice features of Sig's platform design, especially if you own both models.
Witness holes are small openings on the magazine side that line up with each round or increments of rounds. They let you see exactly how many rounds are loaded without removing the magazine from your gun or counting manually. They're numbered in this magazine for quick reference and are particularly helpful during training or competition shooting when you need fast load counts.
