Springfield Armory has expanded its Echelon lineup with the release of the Echelon 4.0C Comp, a compact 9mm pistol designed for concealed carry while still offering a controllable shooting experience. This new model features a 4-inch barrel, a single-port compensator, and a compact frame that closely matches the size and capacity of the Glock 19 long considered the benchmark in this category. At 7.25 inches in overall length and weighing 24 ounces unloaded, the pistol provides a full three-finger firing grip and ships with a 15-round flush-fit magazine, making it a strong option for those seeking a balance between concealability and capacity. One of the standout features of the Echelon series is Springfields Variable Interface System (VIS), which allows shooters to directly mount nearly any popular micro red dot sight to the slide without adapter plates or extra hardware. The pistol ships with RMR pins, and pins for other footprints are available from Springfield, giving users flexibility to select the optic that best suits their needs. The gun is topped with a U-notch rear sight and tritium front sight, offering a clean sight picture even in low-light conditions. The compensator on the 4.0C Comp is designed to reduce muzzle rise and improve follow-up shot speed. While Springfields testing has shown modest improvements, users are encouraged to experiment with various defensive loads including hotter +P-rated ammunition to feel the full benefit. Importantly, the 4.0C Comp fits existing Echelon compact holsters despite the addition of the compensator, simplifying gear selection for those who already own Echelon-compatible rigs. Pairing this firearm with quality carry gear is essential, and Shooting Illustrateds recommended setup includes the JM Custom Kydex Quick Ship AIWB Wing Claw 2.5 holster. This appendix carry rig uses a claw design to reduce printing, features customizable belt attachments, and is available with options like optics cuts and comfort pads. Constructed from durable Kydex in a taco-style pattern, the holster is built for daily use and offers a good balance of concealment and draw speed. The total cost for this holster as configured is around $90, which makes it an affordable yet reliable choice for EDC enthusiasts. Completing the package is the Gideon Optics Granite green-dot sight. This optic offers an 8-MOA dot in a generous 28.3x22.5 mm window and is built with a robust aluminum housing. While its large dot is ideal for competition shooters seeking fast target acquisition, it also performs well for defensive use. The Granite comes with multiple screw sets for slide mounting, a low-profile Picatinny mount for rifle or shotgun use, and the necessary tools and battery to get started right out of the box.
