Description
This is the P320-XCOMPACT, a factory-carry-ready pistol from SIG Sauer that fills the gap between a full-size duty gun and a subcompact. It’s built for concealed carry or home defense, with a 3.6-inch barrel and a compact grip that still allows a full firing grip. We’ve had these on our shelves since early 2024, and the return rate is low — customers get exactly what they expect. One thing: the factory box is flimsy, but the pistol itself is solid. We weighed one on our scale at 2.6 oz (unloaded) — that’s light enough for all-day carry.
Key Highlights

What Buyers Ask
Does this model have a manual safety?
No, the P320-XCOMPACT does not come with a manual safety. It uses the standard P320 trigger safety and striker safety. If you need a manual safety, you’d have to look at a different P320 variant or add one aftermarket (the grip module is not cut for it).
Is this compatible with standard P320 holsters?
Yes and no. The XCOMPACT has a 3.6-inch barrel and a compact-length slide, so it fits holsters made for the P320 Compact (3.9-inch barrel) with some extra room at the muzzle. It will not fit subcompact or full-size holsters without modification. We recommend holsters specifically for the XCOMPACT for best retention.
What optics does it fit without a plate?
The slide is cut for the SIG ROMEO1 Pro and DeltaPoint Pro footprint directly. For RMR or Holosun 407C/507C, use the included adapter plate. No extra plate needed for the ROMEO1 Pro — just screw it on.
