The Rugged Suppressors Obsidian9 is a modular 9mm suppressor for pistols and PCCs, finished here in FDE Cerakote (Rugged Suppressors part no. OBSFDE9). Rugged rates it Belt Fed Rated for pistol calibers up to 9mm, so it is built for sustained fire as well as a few magazines at the range. The ADAPT module changes it from a 7.8-inch standard length to a 4.85-inch short length. The baffles are 17-4 stainless, the tube is hard coat anodized aluminum and the mount is stainless. It is a good fit for shooters who want a tan can on a 9mm pistol or carbine.
