The Springfield Armory Echelon 4.0C Compact 15-Round Gear Pac pairs duty-proven modularity with a layout optimized for capacity-restricted states or low-profile everyday carry. Built entirely around the modular, serialized Central Operating Group (COG) chassis, this pistol drops down to a highly concealable compact frame while keeping a full 4-inch hammer-forged steel barrel. Shipped ready to deploy, the slide features the innovative Variable Interface System (VIS) hosting a pre-installed, co-witnessed Viridian® RFX11 green dot optic. This complete Echelon 15-Round Gear Pac comes safely secured in a heavy-duty nylon zippered pistol bag alongside an expansive loadout of four 15-round flush-fit magazines to guarantee maximum efficiency at the firing line.
