When a duty pistol needs a dependable spare magazine, choosing the right replacement is about fit, feed reliability, and matching the cartridge’s demands. For owners of Sig Sauer polymer-frame striker-fired pistols chambered in stout calibers, having a correct, OEM-fit magazine can mean the difference between a smooth reload and a malfunction at the range or on duty.

Purpose-built replacement for P250 and P320
This replacement magazine is specifically for the Sig Sauer P250 and P320 pistols chambered in 40SW or 357 Sig. That explicit compatibility means the follower geometry, feed lips, and overall length are designed to interface with the factory magazine well of these models. Priced at $36.89, it’s a straightforward way to maintain operational readiness without swapping platforms.

Caliber-specific considerations: .40 S&W and .357 Sig
Both .40 S&W and .357 Sig are high-pressure defensive calibers with different ballistic profiles. .40 S&W offers balanced recoil and terminal performance for service pistols, while .357 Sig delivers higher velocity and flat trajectory from a 9mm-sized bore design. Magazines for these rounds must control cartridge alignment to prevent stovepipes and ensure consistent spring tension to handle the slightly different case profiles and feeding dynamics.
Why this matters in the field
Using a magazine built for the P250/P320 in these calibers reduces the risk of misfeeds and supports reliable function during drills or duty use. The listing notes compatibility with both calibers and the Sig Sauer lineage, so you can expect geometry that matches factory magazines rather than a universal aftermarket compromise.
Fit, spares, and practical advice
Carry at least one spare magazine for training or an operational carry routine. Keep magazines clean, lightly lubricated on the exterior of the spring, and inspect followers for wear. Given the price point of $36.89, it’s reasonable to add an extra magazine to your kit as a low-cost insurance policy.
