Great pics Mr Jon!
I've been meaning to get a KSC SP2009 with SD metal set for some time now but have neglected to do so only because there aren't too many favorable reviews available (if only WA would make an SCW version

). How is its performance on green gas/propane? Reliable? I heard the design of the piston lip is such that it can fold back due to the extra force involved with propane over duster. However, I would think the included piston o-ring in the SD set would remedy this issue. Also, how would you rate its power on propane versus TM, KSC, and WA GBB's? And does anybody know if the SD hybrid set barrel is made from two parts soldered on together (upper port part soldered on top of barrel) or one-piece like WA's hybrid barrels? Apparently SD's TM hi-capa 5.1 hybrid set barrel is made from two soldered parts and has a tendency of breaking apart. Lastly, I heard the recoil spring is very weak and WA 1911 recoil springs will fit and perform better. Could you confirm?
