Also forgot to mention, for people experiences with this new version of the KWA M9, a list of compatible upgrades would be great:
high flow valve
enchanced recoil and hammer spring
6.01 thigh bore
Just thought I'd add that KWA is not a clone of KSC. KSC and KWA are the same company. they use different names for different import/export markets.
