Built around a robust stainless steel chassis, the Echelon Comp 9mm Luger 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 optics mounting 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. The Gear Pac pkg includes four magazines, a Viridian RFX-11 green dot optic and a pistol bag.
