The Springfield Armory Echelon 4.0C Compact CA Compliant Gear Pac brings professional, duty-grade modularity to California handgun owners within a legal, state-approved package. Engineered entirely around the revolutionary, self-contained, and serialized Central Operating Group (COG) chassis, this pistol drops down to a smaller compact frame profile optimized for everyday deep concealment. This exact configuration includes all mandated state safety modifications, featuring a discrete loaded chamber indicator and a factory magazine disconnect safety mechanism. Ready to field right out of the box, the precision-milled slide utilizes a pin-based Variable Interface System (VIS) hosting a pre-installed, co-witnessed Viridian® RFX11 green dot optic. The entire value-driven California-compliant Gear Pac ships completely organized inside a padded nylon zippered range bag loaded with four 10-round factory steel magazines.
