The CSX is built on an aluminum alloy frame with interchangeable polymer back straps, providing the ability to customize the level of concealment and ergonomic fit. Chambered in 9mm, the CSX holds a 12+1 capacity and comes with an additional 10-round magazine for deeper concealment. Designed with flexibility in mind, despite its micro-sized frame, the CSX packs both ambidextrous slide releases and manual safeties.
