Designed for advanced versatility and tactical readiness, the Springfield Echelon 9mm 4.5″ Black 17/20RD U-Dot Sights (EC9459BU) delivers next-gen innovation with proven field reliability. Centered around Springfield’s Central Operating Group (COG)—a serialized, drop-in fire control system—this platform offers complete modularity, allowing for full customization across grip modules.
The 4.5-inch cold hammer-forged barrel ensures repeatable accuracy, while the Melonite®-coated, billet-machined slide features the Variable Interface System (VIS)—Springfield’s patented, optics-ready mounting system that supports direct installation of 30+ red dot optics with no adapter plates.
This variant includes U-Dot tactical sights, combining a tritium/luminescent front with a notch-style tactical rear, designed for fast target acquisition in both daylight and low-light situations. The modular polymer frame features a Picatinny accessory rail, interchangeable backstraps, and Adaptive Grip Texture for reliable control and comfort.
Included are both a 17-round flush-fit and a 20-round extended magazine, giving shooters the flexibility to choose between concealability and capacity.
