Built for low-signature 9mm operations, the Shadow Systems HS923 modular suppressor prioritizes compact deployment and modularity for rapid role changes. Designed for reliability under duress, the HS923 offers a short configuration for tight-handling and an extended baffle stack option for reduced sound signature. The unit ships with a 1/2×28 threaded piston and features an end cap designed to allow the pistol slide to function as a wrench.
