Smith & Wesson CSX E-SERIES 9mm | 3.6in | MFG# 13957

The Smith & Wesson CSX E-Series is a micro-compact, optics-ready 9mm pistol with a 3.6-inch barrel and a modular grip adapter that converts between micro-compact and compact profiles. It features the E-Series flat-faced trigger with a clean break and improved reset, an ambidextrous thumb safety, and a Shield/RMSc optic footprint with a ClearSight cut. An affordable compact red-dot such as the Holosun 507K (under $1,000) pairs well with the CSX E-Series for faster sight acquisition without adding bulk.

Applications: concealed carry (everyday carry) and range training / competition practice.
