Built around a robust stainless steel chassis, the Echelon 4.5F Comp handgun features an integral compensator with a single port on the hammer-forged slide and barrel, reducing muzzle rise for faster, more accurate follow-up shots. The revolutionary Variable Interface System offers unparalleled adaptability with today’s most respected red dot sights, while fully ambidextrous controls and interchangeable backstraps accommodate a broad range of shooters.
