The Tuna Cans 40 Cal / 10mm - L is the longer, higher-capacity version of our hard-use suppressor, built with the same in-house Texas manufacturing, heat-treated 17-4 stainless steel, and no-nonsense design philosophy. This is a serious can made for high round counts and real abuse-without the premium price tag. The L model features a 9-baffle stack with ribbed baffles to increase internal turbulence for strong performance and consistency. The threaded baffle system means each baffle screws together, creating a solid, serviceable stack designed to last.
