Features:

Micro-Compact Concealed Carry Design

The CSX E-Series retains the small footprint and lightweight build of the original CSX, designed to be easily carried concealed without compromising capacity or handling.

Enhanced Trigger

A major upgrade for the E-Series platform is the improved trigger pack, featuring a cleaner, lighter break, shorter reset, and straighter pull path, contributing to better shot control and accuracy for a micro pistol.

Optic-Ready Slide with ClearSight Cut

• The slide comes with an optics cut (RMS-C/507K footprint) to accept compact red-dot sights directly.

• A ClearSight cut directs gases and debris away from the optic window for an unobstructed sight picture and easier cleanup.

Modular Grip & Interchangeable Backstraps

The pistol includes a modular grip adapter and interchangeable backstrap system, letting you tailor the grip size for concealed carry (smaller) or better handling and comfort (larger).

High Capacity for Size

Unlike many micro handguns with single-digit capacities, the CSX E-Series supports double-digit magazine options (up to 17+1 rounds) while still maintaining a compact profile.

Ergonomics & Controls

• Ambidextrous thumb safety and reversible magazine release accommodate left- and right-handed shooters.

• White-dot sights provide a quick target acquisition baseline if not using optics.

Performance

• The CSX E-Series is intended for everyday carry (EDC), self-defense, and general range use, combining metal-frame feel with compact dimensions and respectable capacity.

• Its modular grip design helps shooters of different hand sizes find a comfortable hold.

• Included magazines usually span a range of capacities to suit both deep concealment and maximum firepower options.
