If you've still got those chronically leaking KJW M9 mags, I'll take them off your hands
I am going to buy a TM extended mag for my KJW M9 in a short while, I'll confirm if they work or now.
KSC/KWA is definitely their own design and nothing at all like the TM. Absolutely not a clone.
Regarding the thinness of the material under where the two pins go on KSC/KWA models, that is a design problem that definitely needs to be addressed. Their USP is like that too but it doesn't fail in this manner.
