The Odessa-9 features a 1.1 tube, allowing you to fully utilize your stock sights. It is also fully modular and can be shot in multiple configurations. If you stack only four baffles you’ll be close to, or below, hearing safe levels with subsonic ammunition. With the smaller tube and this much modularity, your suppressed handgun life just got easier. The Odessa-9 is compatible with legacy pistons such as those from Silencerco and Rugged Suppressors. Compatible with 22 LR, 22 Mag, 17 HMR, 5.7x28mm (FNH), 32 AUTO, 380 AUTO and 9mm.
