Frequently Asked Questions
Why does this magazine have an 18-round body but only hold 10 rounds?
This is a California-compliant "blocked" magazine. The full-size 18-round body is permanently restricted to a 10-round capacity to meet California's magazine capacity laws. The full-size body ensures the magazine maintains the correct length and grip feel for the P250 and P320 Full Size frames, so ergonomics and handling remain identical to a standard magazine.
Will this magazine work in both the SIG P250 and P320 Full Size?
Yes. This OEM SIG SAUER magazine is designed to function in both the P250 Full Size and P320 Full Size pistols chambered in .40 S&W or .357 SIG. The modular design shared between these two platforms means the magazine seats, locks, and drops free consistently in either firearm.
Can I use .357 SIG ammunition in a magazine labeled for .40 S&W?
Absolutely. The .357 SIG cartridge is based on a necked-down .40 S&W case, meaning both calibers share the same magazine body and feed geometry. This single magazine is engineered to reliably feed both .40 S&W and .357 SIG rounds, provided your pistol's barrel is chambered for the caliber you intend to shoot.
