The Griffin Armament Revolution 45 Mod 4 Suppressor is a modular .45-caliber handgun silencer engineered for secure mounting, easy maintenance, and flexible length configuration. Built around 17-4 H900 stainless steel baffles inside a 7075-T6 aluminum tube, it uses Griffin’s Carbon-Gard sealed baffle technology and Eco-Flow baffle design to reduce backpressure while keeping fouling locked inside the stack for simpler cleaning.

This user-serviceable suppressor is ideal for .45 ACP pistols and pistol-caliber carbines where shooters want a balance of sound reduction, durability, and low weight. Tool-less disassembly and a forward extension module let you quickly switch between short and full-size configurations to match range use, training, or home-defense setups. Paired with the included EZ-Lok piston and permanently installed booster housing, the Revolution 45 Mod 4 reflects Griffin Armament’s focus on practical innovation and thoughtful craftsmanship.
