The RGW FD917 dummy silencer for the Tokyo Marui G17/ KJ (G17 Gen3) / WE G17 Gen5 GBB pistol can turn your otherwise generic gun into a more futuristic pistol. The dummy silencer also has an inner barrel to help with a slight increase to FPS.
It will NOT fit all G19 and Umarex / VFC G17 Gen3 / Gen 4
