Your Questions Answered
Is this ready for a red dot sight?
Yes. The slide comes optics-ready from the factory. You will need to purchase the specific adapter plate for your chosen micro red dot model (like Sig Romeo1Pro, Leupold DPP, etc.). The slide cut does not include rear iron sights when an optic is mounted.
What magazines does it use?
This California-compliant model ships with 10-round magazines. It is compatible with standard P320 full-size 9mm magazines, but capacity must adhere to local regulations.
How does the XSeries grip differ?
The XSeries grip module has more aggressive texturing on the front, back, and sides than a standard P320 grip. It also features a pronounced beavertail and an undercut trigger guard, which allows for a higher, more secure grip and reduces perceived recoil.

This pistol’s build quality inspires confidence. We had a customer drive three hours to pick one up instead of waiting for shipping, which speaks to its desirability and the certainty of getting exactly what’s advertised. The combination of the optics-ready system, improved ergonomics, and full-size performance makes this a serious option for a compliant, modern handgun.
