At the Range

Having sent roughly 250 rounds of Fiocchi 9mm, 115 Grain FMJ, down range, I experienced no malfunctions with the Sig P320 XFIVE Legion and found it to be accurate.

Overall, I really like how the P320 XFIVE Legion feels in my hands. The grip is comfortable with just the right amount of texturing. If you are not going with a red dot, the fiber optic sights are very good…I like the ability to easily adjust the rear sight for windage and elevation.

Like the entire P320 range of pistols from Sig, the P320 XFIVE Legion has a high bore axis. This theoretically should translate into more felt recoil, but I did not notice any increase in muzzle flip. This may be because the P320 XFIVE Legion is a fairly heavy semi-auto pistol. At 43.5 oz, it weighs significantly more than my 24.7 oz M&P 2.0 full size 9mm pistol.

The Sig P320 XFIVE Legion Trigger

While the P320 XFIVE Legion has a very good trigger, there are two small things that I do not like.

First, I find the reset to be a little too long. And second, as the trigger begins to move forward for the reset, there is a momentary lag/hesitation compared to the Apex triggers in my Smith & Wesson M&Ps.

I could not find the trigger pull weight of the P320 XFIVE Legion on Sig Sauer’s website. What Sig does say on their website is that “The trigger pull of the XFIVE Legion is up to 30% lighter with the new skeletonized trigger”. That said, the trigger pull feels fairly light, which I definitely like.

Final Thoughts

There is no doubt that the Sig P320 XFIVE Legion is a well-engineered 9mm, striker-fired, semi-automatic pistol.

Is it worth the $1,000 price tag? Yes, I think so when you consider all of the innovative features and quality you get for the money.
