The Odessa-9 features a 1.1" tube, allowing you to fully utilize your stock sights. That's right, the Odessa-9 is almost as small as our Mask. It is also fully modular and can be shot in multiple configurations. 11 to be exact (well, 12 if you don't use ANY baffles). If you stack only four baffles you'll be close to, or below, hearing safe levels with subsonic ammunition. Stack on the full 11 baffles and we've hovered just shy of 122dB with HUSH subsonic ammo. With the smaller tube and this much modularity, your suppressed handgun life just got easier.
