Who This Is For
This magazine is ideal for California-based P320 M17 and M18 owners who want an OEM factory magazine that maintains the full ergonomic profile of the original while staying within state-mandated capacity limits. It's also a smart choice for competitive shooters, range enthusiasts, and military or law enforcement personnel stationed in California who demand the same quality component used in the U.S. Armed Forces' standard-issue sidearm.

Frequently Asked Questions
Will this magazine work in my standard P320 Full-Size or P320 Carry, or only the M17/M18?
This magazine is specifically designed and dimensioned for the P320 M17 and M18 models. While it may physically insert into other P320 full-size variants, SIG SAUER recommends using model-specific magazines to ensure proper fit, feeding reliability, and drop-free function. For other P320 configurations, look for magazines explicitly listed as compatible with your specific model.
Is this magazine permanently blocked to 10 rounds, and can it be unblocked?
Yes, this magazine is blocked at the factory to comply with California's 10-round magazine capacity limit. It is sold as a California-compliant product intended for use within the state. The blocking is permanent as sold, and any attempt to alter or remove the block would be a violation of California law. Customers outside of California who need full 21-round capacity should look for the standard unblocked P320 M17/M18 21-round magazine.
Does the coyote tan finish match the SIG SAUER P320 M17 frame exactly?
Yes — the coyote tan finish on this factory OEM magazine is the same color used on the P320 M17's frame and is designed to match seamlessly. Because it's a genuine SIG SAUER factory component, the color is calibrated to the same specification as the pistol itself, giving your M17 a clean, uniform look right out of the box.
