Frequently Asked Questions

Which SIG Sauer magazines is this extension compatible with?

This extension is specifically designed to fit the SIG Sauer P365 X-Macro 17-round magazine. It is not compatible with standard P365 or P365XL magazines, as those have different dimensions. Always verify your magazine model before purchasing to ensure a proper fit.

Will this extension affect the concealability of my P365 X-Macro?

Tyrant CNC engineered this extension to closely match the existing contours of the P365 X-Macro frame, keeping the added length to a minimum. While any extension will add a small amount of grip length, the low-profile design significantly reduces the risk of printing through clothing compared to aftermarket options with less thoughtful geometry.

Is this magazine extension legal to use in California?

California law restricts detachable magazines to a maximum of 10 rounds. Because this extension brings total capacity to 20+1 rounds, the resulting magazine configuration exceeds California's legal limit and may not be compliant for purchase or possession in the state. Customers in California should consult local regulations and seek legal advice before purchasing any high-capacity magazine accessory.
