GSL’s signature Python Piston Adapter is available several thread pitches for pistons and 9mm and 45cal PCCs.
When using the python with a fixed barrel weapon, and fixed spacer is required instead of the python spring.
This piston is designed for the GSL Python Suppressor, and it might work with the GEMTECH Lunar 45 or Blackside 45 depending on how long ago they were built.
It will NOT work in the GSL Stealth or Legend 9mm Suppressors.
