Description
The Sig Sauer P320 X-Compact is a modular, optics-ready 9mm pistol designed for concealed carry and duty use. It bridges the gap between full-size capability and compact concealment, featuring the proven P320 fire control unit in an X-Series grip module. Since we added it to our inventory in January 2026, it has consistently been a top seller and a regular reorder item for our shop.
Stand-Out Features
- Modular Fire Control Unit (FCU): The serialized trigger group is the firearm. It can be swapped into different grip modules and slides, allowing for extensive customization.
- Optics-Ready Slide: The slide is cut from the factory to accept Sig Sauer’s Romeo1Pro and other popular micro red dot sights without an adapter plate.
- X-Series Grip Module: Features an aggressive texture, undercut trigger guard, and flared magwell for improved control and faster reloads.
- Flat X-Series Trigger: Provides a clean, consistent break and short reset for improved shot-to-shot speed.
- Compatible Sights: Our staff has confirmed the slide works with both factory Sig sights and aftermarket options from Trijicon and AmeriGlo.

Your Questions Answered
Does this model have a manual safety?
This specific SKU is the standard model and does not include a manual safety. The P320 X-Compact is also available in a Manual Safety (MS) version with a different model number.
What holsters fit the P320 X-Compact?
It fits holsters designed for the P320 Compact/Carry models, but verify compatibility for light-bearing holsters. The X-Series grip module and optics-ready slide are the primary fit considerations.
Can I use full-size P320 magazines?
Yes. The X-Compact accepts all standard P320 9mm magazines. Full-size 17-round and 21-round magazines will extend past the grip but function reliably.
