The SIG SAUER P365 9mm Magazine delivers the reliability and precision engineering that SIG SAUER is known for, now in a California-compliant 10-round configuration — giving Golden State shooters a purpose-built option for their everyday carry P365.

  • Factory-blocked to 10 rounds with a permanently riveted base plate for California compliance
  • Built on a 17-round body, providing a longer grip surface and improved control
  • Compatible with the standard SIG SAUER P365 — not compatible with the P365 X-Macro due to the fixed base plate
  • Constructed from high-quality steel and polymer components for long-term durability
  • Feeds 9mm Luger reliably with a precision-fit follower and consistent spring tension
  • Genuine OEM SIG SAUER magazine, maintaining the quality standard the brand is known for

Who This Is For

This magazine is ideal for California residents who own a SIG SAUER P365 and need a legally compliant, high-quality replacement or spare magazine. Whether you're a daily concealed carrier, a range shooter, or a new P365 owner stocking up on essentials, this blocked 10-round mag offers the full-size grip feel of the 17-round body while keeping you on the right side of California's magazine capacity laws. Note: if you own a P365 X-Macro, this magazine is not compatible without changing grip extensions — be sure to select the correct variant for your specific firearm.

Frequently Asked Questions

Will this magazine fit my SIG SAUER P365 X-Macro?

No. Although this magazine is built on the same 17-round body used in some X-Macro configurations, the permanently riveted base plate prevents it from seating correctly in the P365 X-Macro without swapping grip extensions. This magazine is designed and sold specifically for the standard SIG SAUER P365. If you own an X-Macro, please select the appropriate X-Macro compatible 10/17 magazine from our store.

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

The base plate has been permanently riveted at our store to block the magazine to 10 rounds in compliance with California's magazine capacity restriction laws. This modification is intentional and permanent — the base plate should not be removed or altered. Attempting to do so may render the magazine non-functional and could have legal consequences under California law.

Is this an OEM SIG SAUER magazine or an aftermarket product?

This is a genuine, factory-original SIG SAUER magazine. The blocking and base plate riveting are performed after the fact to ensure California compliance, but the magazine itself is the same high-quality OEM component used in standard P365 pistols. You can expect the same reliable feeding, fit, and finish as any other authentic SIG SAUER accessory.

    Nice to be able to purchase this item. Fits great in my hand. The extra magazine length with cover is comfortable.
