The KSG410 uses a bullpup layout with ambidextrous, centrally located controls and a cross-bolt safety. Bottom loading and downward ejection simplify operation for both right- and left-handed users while keeping the overall length to 26.1 in.
Its dual internal magazine tubes are user-selectable with a manual magazine selector. Capacity is 5+5+1 with 3 in shells and 7+7+1 with 2.5 in shells, providing flexible load options in a lightweight .410 platform.
The integrated carry handle doubles as a heat shield and sighting rib, and includes M-LOK slots for compatible accessories. Sight alignment is fast with the fiber-optic front sight and rear notch built into the carry handle. The polymer forend features the familiar KSG-style square texture for a secure pump stroke.
Construction centers on an 18.5 in steel barrel and a metal serialized receiver tube finished in gray, housed within a glass-fiber-reinforced polymer chassis finished in green. The 3 in chamber broadens ammunition compatibility. Additional details include a 13.75 in length of pull, an unloaded weight of approximately 5.4 lb, and the patent legend US D892964 S on the carry handle. This example includes removable black textured grip tape on the pistol grip and cheekpiece (sides and top) for added traction without altering the factory components.
