This Sig Sauer P320 X5 Legion pistol is for sale. The slide features front and rear angled cocking serrations, adjustable Dawson Precision® fiber-optic sights, and an optics cut where the rear sight sits. The TXG Tungsten-infused grip module brings the pistol to 43.5 oz. with an empty magazine; this gives you around 50% less muzzle flip according to Sig Sauer. The skeletonized Legion flat-faced trigger is up to 30% lighter. The detachable magwell aids in quick magazine changes and can be removed for better concealment.
