The Smith & Wesson CSX E-Series is an optic-ready micro-compact 9mm pistol designed for everyday concealed carry and close-range defensive use. It pairs a short 3.6″ stainless steel barrel with a modular grip adapter so users can size the grip to match carry or handling preferences. The platform emphasizes a refined trigger feel and options for three factory magazines to suit different carry setups.
Modular grip adapter – The included adapter converts the grip between micro-compact and compact profiles to tailor concealment or handling. E-Series trigger – An enhanced trigger design provides a clean break and an improved reset to support consistent follow-up shots. Optics-ready – The slide is cut for a modified RMS-C/507K (Shield/RMSc) footprint and features a ClearSight cut on the slide.
