Editor’s Note

“The XTEN is a natural evolution of the P320 line into 10mm. Sig applied their know-how when scaling the platform up, so the end result is an accurate shooter that isn’t too much to handle.” – Sean Curtis

By The Numbers - Sig Sauer P320-XTEN

Once you get beyond the muzzle flip and focus on fundamentals, the 5-inch bull barrel does a great job of putting together accurate shots.
We had zero failures across multiple ammo types during our testing.
The P320 is extremely customizable, but the XTEN only allows you to swap out parts with .45 ACP sized components.
Fitting both large and smaller hands, Sig did an excellent job of hitting the middle ground with the grip.

Smith & Wesson M&P 2.0 10mm

Smith & Wesson M&P 2.0 10mm


Smith and Wesson finally decided to revisit the 10mm cartridge and adapted their M&P 2.0 platform for it. Our test gun was reliable, shot well, and had the quality ergonomics the M&P line is known for. However, there have been some reported issues with the 4-inch models, and it should be noted that this is still a relatively new gun in Smith and Wesson’s lineup.

Sig Sauer P320

Sig Sauer P320


The Sig P320 is a great pistol and an alternative for Glock, XD, M&P.  For a Sig, it’s an entry-level gun and quite subpar compared to Sig’s legacy P-series. That said, this gun is reliable, accurate, and modular. As the Army’s newest sidearm, the P320 is a good choice for a first pistol and/or carry gun.

The P320 comes in different models and calibers. For gamers, the RX model is equipped with a factory red dot that looks promising. The Tacops Carry model is perfect for conceal carry with it’s full-length grip, compact slide, tall SIGLITE Night Sights, and 21-rd mags.

final verdict

“I found the XTEN to be accurate and reliable, with great ergonomics, and it was not too much to handle. Notably, firing 9mm after shooting the XTEN seemed almost mundane.” – Sean Curtis
