Description
We started stocking the new P320-XFULL in summer 2025, and it’s been a regular reorder item ever since. This is a full-size, optics-ready pistol built for shooters who want a flat-shooting, high-capacity platform right out of the box. We’ve sold over 147 of these, and they keep moving because they work. The key benefit: you get a drop-in fit on every frame we tested — no fitting required. That’s not marketing talk; we checked it on our bench. If you need a duty-grade handgun that’s ready to run, this is it.

What Buyers Ask
Does this fit standard P320 holsters?
Yes, the XFULL uses the same frame dimensions as the standard P320 full-size. Any holster molded for a P320 full-size with a 4.7-inch barrel will work. We’ve tested it with several popular brands.
Can I swap the grip module for a smaller one?
Yes. The fire control unit is interchangeable with any P320 grip module. You can go to a compact or carry size grip if you want. It takes about two minutes with a punch tool.
What optics are compatible without an adapter plate?
The slide is cut for the Delta Point Pro and Romeo1 Pro footprint. For other optics like the RMR or Holosun 407C/507C, you’ll need an adapter plate. Those are available separately.
