Hi guys I have this KWC M9 gas blowback. 
The slide is metal along with the internals, the gun it’s self shoots perfectly very responsive with a great kick good power to it being Co2. 
However there is a issue with the mag the Co2 canister is stuck inside the head on the screw from underneath that you would normally turn is fine so not chewed out. But when you turn it the screw just spins. 
I tried my friends mag from the same pistol and it fires excellently.
So basically the pistol works fine but the mag needs looking at. 
The pistol is in used condition but apart from the mag it’s all complete nothing missing or broken. Also comes with the padded pistol case in the pic. 
I’ve priced it low to take into account the mag needs sorting or replacing. 
Looking for £40.00 collected from Birmingham or £45.00 posted.
