The Springfield Armory Gear Pac Echelon 4.0C Handgun delivers a carry-oriented 9mm platform from Springfield Armorys Echelon series that blends a 4" hammer-forged steel barrel with a Melonite finish and an optics-ready billet machined slide to give shooters a rugged, accurate pistol for everyday carry, range sessions, and defensive use. The factory-installed Viridian RFX11 green dot with Instant-On and a 30,000-hour runtime provides immediate, intuitive aiming in dynamic situations while white-dot front, Tactical Rack U-Dot rear and tritium night sights maintain sight picture if you operate without the dot; the slim 1.2" grip width, lightweight polymer small grip module and captive recoil system make follow-up shots manageable and comfortable. At roughly 24 ounces with a flush magazine and just over seven inches in overall length, the Echelon 4.0C balances concealability and control for on- and off-body carry, range drills, and home defense, and it ships in a heavy-duty nylon pistol bag for secure transport. This FFL-required firearm ships ready for optics and duty use, offering a practical, modern service-style 9mm built for serious shooters.
