Frequently Asked Questions
Will this magazine fit both the SIG P250 and P320 Full Size?
Yes. This magazine is designed to fit both the SIG SAUER P250 Full Size and the P320 Full Size platforms. Because the P250 and P320 share the same grip module and magazine well dimensions in the full-size configuration, this OEM magazine provides a precise, drop-free fit in either pistol. Always confirm your pistol's frame size is Full Size before ordering, as compact or subcompact variants use different magazines.
Why does a 10-round magazine have a 14-round body?
This magazine uses the standard full-size 14-round body but is blocked internally to hold a maximum of 10 rounds, making it compliant with California's magazine capacity restrictions. The full-size body ensures the magazine still seats flush and functions correctly in your Full Size frame, maintaining the original ergonomics and handling of your firearm without modification.
Can this magazine be used with both .40 S&W and .357 SIG ammunition interchangeably?
Yes — .357 SIG and .40 S&W share the same case head diameter and feed from the same magazine design, which is why this single magazine is rated for both calibers. If you switch calibers, you will need to swap your barrel, but the magazine itself can remain the same. Always verify your pistol's barrel and chambering before switching ammunition types.
