What was up was the entire “X-series” of P320 variants. We got a chance to get in a little range time with all three variants of the X-series and to hear some back story on how the entire project came to fruition.

It seems that SIG had hired former USPSA President Phil Strader as the product manager for the P320 line. Further, SIG exposed the P320 to a lot of racing at USPSA matches in the hands of its shooting team, headed by legendary pistolsmith and shooter, Bruce Gray.

As the saying goes, “racing improves the breed”, and no doubt much of what had been learned over that time turned up in this new X-series of pistols. The flagship of the trio was the X-Five, obviously devised as a turnkey solution to going racing with a P320. Shootable in USPSA Limited or, by the expedient of removing the mag-well extension, Production, the gun was intended to be competitive right out of the box.

With range buddy Mike Grasso along to serve as a control, we timed five-round strings of fire into an 8-inch circle at 7 yards. To eliminate as many variables as possible, the shooter was allowed to start aimed in on the circle with their finger on the trigger.

After warming up, we ran three runs in each of three configurations to get some non-scientific averages: X-Carry slide and trigger in P320C frame, X-Carry in stock configuration, and then X-Carry with the Grayguns trigger group. Across the three setups, my average strings went from 2.51 seconds with the Boresight Solutions P320C frame to 2.37 with the stock X-Carry to 2.04 with the Grayguns trigger in the SIG Sauer P320 X-Carry.
