Springfield Armory Echelon Alpha 4.0C 9mm Luger 4in Black Melonite Pistol - 10+1 Rounds - Califonia Compliant - Designed for discreet everyday carry, the Echelon 4.0C Alpha offers an accessible entry into a modern personal defense platform. Its compact frame and 4-inch barrel create a streamlined, carry-friendly profile, while the Variable Interface System allows direct compatibility with many of today's most popular red dot optics. The U-Dot sight system promotes quick target acquisition, and at the heart of the pistol, the serialized Central Operating Group provides a durable, modular foundation. This California-compliant configuration includes a 10 Round Magazine, magazine disconnect, and loaded chamber indicator. Recontoured Slide : The recontoured slide is precision forged and Melonite finished for durability, with deep, aggressive serrations for easy manipulation; Ambidextrous :The Echelon Alpha is equipped with an ambidextrous slide stop and magazine release for intuitive use; U-Dot Sights: The Echelon Alpha features a high visibility white-dot front sight paired with a Tactical Rack U-Notch rear; Stainless Steel Magazine : The Echelon Alpha ships with one flush-fitting stainless steel magazine; Central Operating Group : Precision-built from stainless steel using advanced manufacturing methods, this serialized chassis can be easily removed and paired with different grip modules and slides, allowing you to quickly reconfigure the Alpha across the Echelon platform; Poymer Cover Plate : When no optic is installed, the included cover plate seamlessly fills the space for a clean, finished slide profile; Hammer Forged Barrel : Hammer forging produces a stronger, smoother bore for improved accuracy and service life, while the Melonite finish adds corrosion and wear resistance; Oversized Trigger Guard : Oversized for use with gloved hands, the Echelon Alpha features an enlarged trigger guard that is undercut; Adaptive Grip Texture : Developed for the challenges of concealed carry, the Adaptive Grip Texture feels smooth to the touch until you apply pressure and engage the more aggressive texture just below the surface; Textured Indexing Points : Common indexing points on the Echelon Alpha are textured for an extra-firm grip; Self Locking Front Pins : The Variable Interface System uses patent-pending self-locking pins to deliver one of the most advanced optics mounting systems available. As the mounting screws are torqued to spec, the pins apply lateral pressure to the optic's interior mounting surface, eliminating variance and left/right movement. The result is an unparalleled fit between the slide and a wide range of optics; Stainless Steel Magazine: The Echelon Alpha ships with one flush-fitting stainless steel magazine;
