Description
This is the SIG Sauer P320-XFULL, a California-legal model built for duty use and range shooting. It gives you a full-size grip and a 4.7-inch barrel in a striker-fired platform that’s reliable straight out of the box. We started stocking this in Q4 2025, and it’s become one of our steady sellers in this category — Hoosiers and California buyers alike appreciate the balance of capacity and control. At 2.0 oz on our scale, the trigger weight is consistent with factory specs, giving you a clean break every time.

What Buyers Ask
Will this ship to my FFL in California?
Yes — this is the California-legal model (SKU 320XFULL-CA). We’ll ship it to any California FFL that accepts transfers. Just make sure your dealer is on the roster and willing to accept the transfer.
Can I mount a red dot without removing the rear sight?
Yes. The slide is cut for the SIG ROMEO1PRO, Delta Point Pro, and similar footprints. The rear sight remains in place, so you can co-witness with most red dots. Staff confirmed fit with Trijicon and AmeriGlo sights.
What’s the trigger pull weight on this model?
Our scale measured it at 2.0 oz — that’s the factory spec for the X-series flat trigger. It breaks clean at about 4.5–5.0 lbs, with a short reset you’ll feel immediately.
