awesome review colin, I really want one of those to compare with my KSC M9 1st gen (send one my way?
the PTP seems to be only a marketing term used by KWA since KSC is only calling theirs the new version (also full metal)
from what I've read the only thing different from the old one is the blowback chamber and the new mag design
it's a shame they left the outer barrel plastic
just a note: WA M9's and the old KSC/KWA M9's are all capable of decocking too
360fps... wow that's amazing
but are you sure the sights are non-adjustable?
