Smith & Wesson CSX E-Series Micro 9mm — aluminum-frame, single-action, optics-ready pistol
The Smith & Wesson CSX E-Series combines a lightweight CNC-machined aluminum frame with a crisp single-action trigger in a micro-compact 9mm package. An Armornite-finished slide that is factory cut for RMS-C or Holosun 507K optics, fully ambidextrous controls, and modular front-strap adapters give this pistol a modern feature set rarely found in an alloy-frame carry gun.

This E-Series CSX uses a flat-faced trigger with an integral safety blade that delivers a straighter pull and shorter reset than the original CSX design. The skeletonized hammer complements the single-action-only system for a consistent, 1911-style break in a sub-compact footprint.
The optics-ready slide features forward and rear cocking serrations plus ClearSight gas-diversion ports around the RMS-C / 507K footprint, helping keep the lens clear during firing. Steel white-dot sights are installed for out-of-the-box accuracy when a red-dot is not in use.
Both the slide and aluminum frame wear Smith & Wesson’s matte black Armornite finish for corrosion resistance. Ambidextrous thumb safeties and a bilateral slide stop make the pistol fully left- or right-hand friendly straight from the factory.
A modular front-strap adapter lets the shooter tailor grip length while keeping the CSX’s micro-size profile. Despite its 3.1-inch stainless steel barrel, the double-stack design yields 15+1 capacity, giving this micro 9mm service-pistol firepower in a concealed-carry size.
