The X-FIVE SXG series pairs a stainless-steel slide and a stainless-steel SXG grip module, both finished in Legion Gray PVD, for a cohesive, durable build. The grip module adds an extended beavertail and a flared magwell for confident handling during reloads.
The optics-ready slide includes a removable rear-sight plate, three top lightening windows, and front and rear serrations. Sight alignment is fast and precise thanks to a fully adjustable rear sight and a green fiber-optic front.
Its 5-inch match bull barrel, striker-fired action, and flat skeletonized trigger are configured for consistency and control. A 1911-style recoil system with interchangeable springs allows tuning to ammunition or preference.
The full-length dust cover integrates a 1913 Picatinny accessory rail, and the modular P320 FCU architecture is retained, with the manufacturer mark listed as Newington, NH, USA. Capacity is 21+1, and unloaded weight is approximately 49–50 oz per factory information.
