The Griffin Armament Griffin 3L1351LHSIG 3 Lug Adapter 9mm 13.5x1LH converts a properly threaded 9mm SIG host into a smooth, repeatable 3-lug mounting interface for your suppressor. Machined from durable stainless steel and treated with a Melonite QPQ finish, this compact adapter is built to handle regular range use while maintaining precise alignment at the muzzle.

This adapter is ideal for shooters who want fast on/off suppressor attachment without constantly threading and unthreading their can. Designed around the common HK-pattern 3-lug standard, it works with compatible 3-lug silencers and Griffin 3-lug interface assemblies, making it a practical upgrade for range sessions, training, or recreational shooting. Its quality construction reflects Griffin Armament’s focus on reliable, shooter-focused suppressor accessories.
