The KJWorks CZ P-09 GBB Airsoft Pistol is really almost exactly like the ASG Distributed version since both are made by KJWorks at the end of the day. There are some slight differences between them like CO2 versus Green Gas and some other very minimal cosmetic changes. I would say go with which ever version is in stock and perhaps is less expensive at the time. You really can’t go wrong as this is a great choice to make for an Airsoft Side arm to use on the Airsoft field or for plinking in your yard or indoor range.
