Springfield Armory Echelon 4.5F Optic Ready 9mm Pistol with Aimpoint COA - 4.5" - 1x 17rd, 1x 20rd Mags

The Springfield Armory Echelon 4.5F is Springfield's flagship duty-grade 9mm, a full-size pistol built around a stainless steel modular chassis and the Variable Interface System optics mounting found across the Echelon line.

Features:

• 9mm, 4.5" barrel
• One 17-round flush-fit magazine and one 20-round extended magazine included
• Factory-installed Aimpoint COA closed-emitter red dot via the Aimpoint A-CUT direct slide interface, no adapter plates
• Hammer-forged barrel with a Melonite finish, 1:10 twist
• Medium polymer grip module, 1.2" grip width, compatible with medium Echelon grip modules
• Captive recoil system
• Billet-machined slide with a Melonite finish
• 24.6 oz with the flush magazine

The Variable Interface System slide cut accepts more than 30 pistol red dot sights with no adapter plates, using self-locking front pins that keep the optic from shifting side to side. The Central Operating Group's serialized stainless steel chassis lets you swap frames, and its tool steel trigger components give a clean, crisp trigger for a striker-fired pistol.

Springfield offers the Echelon 4.5F in black, OD Green, and FDE, with an integral compensator or a factory-mounted Aimpoint COA or Viridian RFX11, and with 10, 15, and 17/20-round magazine packages. The features above list what this version includes.

Springfield Armory has built firearms in the USA since reviving the historic name in the 1970s, and it backs its firearms with a lifetime warranty against defects in materials and workmanship.
