The Tuna Cans 9mm – L is the longer, higher-capacity version of our hard-use stainless 9mm can—built for shooters who want more baffles, more volume, and more performance while keeping the same rugged 17-4 construction.
Made from heat-treated 17-4 stainless steel, the L model is designed for serious firing schedules and long-term durability. Up front, it includes a 3″ blast chamber built to handle large mounting systems—including tri-lugs and piston boosters—giving you flexibility across PCCs and pistol setups.
