Engineered for carry, the Echelon™ 4.0C retains the key features of the full-size model, with a shorter 4-inch barrel and compact frame for enhanced concealability.
Its revolutionary Variable Interface System provides unmatched direct-mount compatibility with today's leading red dot sights, complemented by U-Dot irons for fast target acquisition.

At the heart of the Echelon lies the all-new Central Operating Group.Employing cutting edge manufacturing techniques, the Central Operating Group is entirely self-contained and serialized allowing it to be easily moved between grip modules in seconds
Precision built from stainless steel, the chassis provides a robust housing for its patent-pending operating system. Concealed beneath the slide cover plate is the Echelon’s patent-pending optic mounting system. The Variable Interface System allows users to mount over 30 optics directly to the slide without the use of adapter plates.

The serialized Central Operating Group is housed in a compact frame, offering a 15-round capacity with the flush magazine and 18 rounds with the extended magazine.
