Frequently Asked Questions

The P365X uses standard SIG Sauer P365 magazines. It ships with one 12-round flush-fit magazine. All P365-series magazines are interchangeable.
How does it differ from the standard P365?
The P365X features the optics-ready slide from the P365 SAS and the XSeries grip module with a flat trigger. This combines the optic capability with an enhanced grip texture and trigger feel.
