The Dead Air Odessa 9 Replacement Piston, M13.5×1 LH is the piston for running the Odessa 9 on a tilting-barrel handgun with a 9mm barrel cut to a left-hand metric thread (Dead Air part no. DD441). Dead Air Silencers lists the thread as M13.5-1LH and makes the Odessa 9 piston in two thread sizes. A left-hand metric thread does not interchange with the 1/2-28 option, so the thread has to match your barrel. It also makes a sound spare for any Odessa 9 owner whose host pistol is threaded this way.

Key Specifications

• The thread pitch is M13.5×1 LH, a left-hand metric thread that must match your pistol barrel.
• The through bore is 9mm, sized for 9mm barrels.
• It is made for the Odessa 9 suppressor, so it is the piston for that host.
• The use is tilting-barrel handguns, which is what Dead Air makes the Odessa 9 piston for.
• The other thread option is 1/2-28, sold as its own item, so a left-hand metric barrel needs this one.
• Dead Air makes this piston in two thread sizes, so the thread is the choice you have to get right.
• Dead Air also makes the Odessa 9 fixed mount in the same two thread options, the alternative mounting style.
