A dependable spare magazine is one of the simplest and most important upgrades you can add to a defensive or range kit. When you need fast reloads and consistent feeding, a purpose-built replacement magazine maintains reliability and extends service life for your pistol platform.
SIG SAUER P250/P320 replacement magazines are made for Sig Sauer P250 and P320 pistols chambered in 40SW or 357 Sig. Shop this product
Performance and fit
These magazines are specified as replacement components for the SIG SAUER P250/P320 family. That compatibility is critical: magazines that match the feed lips, follower profile, and lockup of the P250 and P320 deliver consistent feeding cycles and lockwork interaction. For owners of various Sig Sauer models in these calibers, having a spare magazine tailored to the platform reduces the chance of stovepipes, double feeds, or failures to feed.
Understanding the calibers: 40 S&W and 357 Sig
The listing specifically covers magazines for pistols chambered in 40SW and 357 Sig. Both calibers are popular for defensive use: 40 S&W balances magazine capacity with larger-diameter projectiles and proven terminal performance, while 357 Sig aims to replicate 357 Magnum performance in a semi-auto cartridge, offering high velocity and strong penetration in the right loads. A magazine built for these cartridges must account for brass thickness and bullet profile to maintain smooth stacking and reliable extension into the feed ramp.
When you select this replacement magazine, you’re retaining the correct geometry for those rounds so performance stays consistent with factory expectations. View product details and pricing
Installation, maintenance, and practical tips
Install the magazine by inserting and ensuring the mag catch fully engages. Periodically inspect the follower and spring for wear, and clean with a brush and solvent if debris accumulates. Rotate magazines in your service rotation to prevent spring fatigue and verify function with dummy rounds or live-fire drills at the range.
