The G series has undergone many minor changes since the first generation appeared in 1982. The fourth-generation "17 Gen.4" is finally here as a gas blowback!
The reproducibility is improved by measuring the genuine parts, such as the new grip checker ring, the larger magazine catch, and the removable grip back strap that was adopted for the first time in the 4th generation. In addition, the new Glow 19 blowback engine has been inherited to achieve more powerful blowback and efficient operation.

  • Large diameter cylinder adopted:
    Inheriting the new 19 blowback engine, the internal structure has been completely refined. By adopting a cylinder with a diameter of 15 mm, we have achieved stable actual shooting performance and powerful blowback.
  • Improved reproducibility:
    Pursuing the reality of size and detail based on the data measured from the real "17 Gen.4". In addition, we are particular about reproducing the texture of the details, such as reproducing the dual recoil spring and separating the extractor (*) and the slide cover plate as separate parts. * This is a dummy simulating only the appearance.
  • Gen.4 style railed frame:
    A new type of anti-skid is used for the frame that integrates a 20mm wide underrail that allows the installation of lights that are essential for CQB equipment. In addition, it comes with 2 types x 2 size back straps, and it is possible to change the grip size to 3 levels including the unattached state.
  • Lanyard link:
    The lanyard link at the rear of the grip can be connected to a lanyard (= bearer string) that prevents it from being lost or dropped.
  • Cocking indicator:
    It is equipped with a gimmick that allows you to easily determine whether the main body is ready to be fired, depending on the rest position of the trigger.
  • Die-cast magazine:
    Includes 25 magazines and a die-cast magazine resistant to cold.
