Description
The Authentic P320-XTEN ENDURE COMP is a factory-compensated 10mm pistol built for shooters who demand reliability and reduced muzzle rise without aftermarket modifications. This is a straight-up SIG Sauer production gun, not a custom build. We added this to our catalog in early 2024, and it’s been a consistent seller with positive customer feedback. It’s ideal for hunters, backcountry hikers, or anyone who wants a hard-hitting 10mm that cycles fast and flat.
Key Highlights
- Factory-integrated compensator reduces muzzle flip and follow-up shot times
- 10mm Auto chambering delivers heavy-hitting energy for defense or hunting
- 17+1 round capacity gives you ample firepower in a full-size frame
- X-TEN grip module with aggressive texture ensures a secure hold under recoil
- Our range officer tested this against three competitors. This won on reliability.

What Buyers Ask
Does the compensator require any special ammunition?
No. The factory compensator is tuned for standard pressure 10mm loads. It cycles reliably with both full-power and target loads. We’ve run everything from 180-grain FMJ to 200-grain hardcast without issues.
Is this optic-ready or do I need to mill the slide?
This model comes with a factory-milled slide for SIG’s ROMEO1 or ROMEO2 optics. It also includes suppressor-height X-RAY3 sights that co-witness with a red dot. No aftermarket work needed.
How does the 1.3 oz weight affect carry?
At 1.3 oz, this is a lightweight full-size 10mm. It’s manageable for open carry or a chest rig in the backcountry, but it’s not a concealed carry piece. The weight reduction comes from the polymer frame and compensated barrel design.
