  • California-compliant 10-round capacity, permanently blocked and riveted from a 17-round body
  • Fits the SIG SAUER P365 XL exclusively due to the fixed extended base plate
  • Constructed from high-quality steel and polymer components for long-term durability
  • Precision-manufactured feed lips ensure consistent, reliable 9mm chambering every round
  • OEM SIG SAUER quality guarantees a drop-free, secure fit in your P365 XL
  • Riveted base plate prevents modification, ensuring permanent legal compliance

Who This Is For

This magazine is the ideal choice for California-based SIG SAUER P365 XL owners who need a legally compliant, drop-in replacement or spare magazine. Whether you carry concealed daily or visit the range regularly, this blocked mag gives you the reliability of a genuine SIG SAUER product within the bounds of California's magazine capacity laws. Note: due to the riveted extended base plate, this magazine will not fit a standard P365 without a grip module or extension change — P365 owners should select the appropriate 10/17 P365 variant instead.

Frequently Asked Questions

Will this magazine fit a standard SIG SAUER P365 (non-XL)?

No. Because this magazine uses the riveted extended base plate from the 17-round P365 XL body, it will not seat correctly in a standard P365 grip module without a grip extension or module change. If you own a standard P365, please select the dedicated P365 10/17 blocked magazine variant instead to ensure a proper fit.

Why is the base plate riveted and can it be removed?

The base plate is permanently riveted as part of the blocking process to ensure the magazine cannot be converted back to its original 17-round capacity. This modification is intentional and required for California compliance. Attempting to remove or alter the rivet or base plate would compromise both the structural integrity of the magazine and its legal status under California law.

Is this magazine legal to purchase and use in California?

Yes. This magazine has been permanently blocked to 10 rounds and riveted prior to sale, making it compliant with California's magazine capacity restrictions. It is sold specifically as a California-compliant product by Goodland Guns, a California-based retailer. As always, buyers are encouraged to stay informed of any changes to local ordinances that may apply to their specific jurisdiction within the state.
