Springfield Armory Echelon Alpha 4.0C RAD Chameleon Features The Springfield Armory Echelon Alpha 4.0C RAD Chameleon takes the Echelon s modular design and pairs it with the U-Dot sight system giving shooters a rear notch paired with a fiber optic front dot for quick intuitive alignment under stress. The Echelon platform was built from the ground up as a modern striker fired pistol with an optics-ready slide so this variant carries that same adaptability into a compact-size package. The Chameleon finish gives the pistol a distinctive visual identity that stands apart from a standard factory configuration. Chambered in 9mm Luger it is built to handle a wide range of factory defensive and practice ammunition. This Echelon Alpha ships with a single 15-round magazine giving the shooter a strong capacity to work with for range sessions or carry use. The 4.0C designation reflects Springfield s compact-size Echelon variant balancing a shorter more concealable frame with the platform s full-size features. Shooters looking for a modern optics-ready 9mm with a unique finish and fast sighting system will find the Echelon Alpha 4.0C RAD Chameleon a strong option available for sale at GrabAGun.
