SIG Sauer, fresh off the Army’s selection of a P320 variant as the U.S. XM17, has been making some tweaks to its striker-fired P320s called the X-Series. There are three guns so far, starting with the X-Five, a 5" gun designed with competitors in mind. The lockwork is based on the P320, but it has been upgraded with a flat-faced, more in-line trigger. It has fully adjustable sights, a more ergonomic frame, a flared magazine well and can accept weights in the back of the grip to help tame recoil. It comes with a 21-round magazine. Rounding out the X-Series is the Carry, with a 3.9" barrel, and the V-TAC, which has a 4.7" barrel. The latter was made to Delta operator Kyle Lamb’s specifications. sigsauer.com
