Get P320-XFULL Online
We started stocking the P320-XFULL in spring 2025, and it’s become one of our steady sellers in this category. This full-size, optics-ready pistol is built for shooters who want a flat-shooting, high-capacity platform straight out of the box. The XFULL grip module and crisp X-Series trigger give you a solid, comfortable hold and a clean break every time. Staff note: this is the model we personally use in our shop demo Glock. Says enough.
Key Highlights
- Full-Size Frame, Modular Design — The XFULL grip module fits most hands well and accepts 17-round magazines. Swap grip modules in seconds to change fit or color.
- Optics Ready Slide — Factory-milled to accept popular red dot optics without adapter plates. Shoot with irons or add a dot—your call.
- X-Series Flat Trigger — Clean, short reset with a flat face that keeps your finger indexed consistently. Improves accuracy shot after shot.
- Night Sights Included — Comes with SIG’s X-RAY3 day/night sights. Green front dot and rear dots glow for low-light shooting.
- Holster-Friendly Design — No sharp edges or weird protrusions. Fits most standard P320 holsters.

What Buyers Ask
Will this fit my existing P320 holster?
Yes, the XFULL uses the same slide profile and trigger guard as the standard P320 full-size. Most holsters made for the P320 full-size (including Safariland, Blackhawk, and Kydex customs) will work. The XFULL grip module is slightly different at the dust cover, but that rarely affects holster fit. If in doubt, bring it by our shop and we’ll test it.
Does it come with a case and extra mag?
Yes. Your P320-XFULL ships in a SIG branded hard case with one 17-round magazine, cable lock, and owner’s manual. We also include a free Indiana Gunshop sticker and a card with our direct line if you have any questions.
Is the slide cut for any specific red dot?
The slide is cut for the SIG ROMEO1 PRO footprint. That also fits the Leupold DeltaPoint Pro and Holosun 507K/407K with the right screws. If you’re running a different dot, we can advise on adapter plates or direct milling. Call or email us before ordering if you’re unsure.
