KSC Glock 18C questions
 

I recently acquired a KSC Glock 18C and I have a few questions.

It didn't come with the allen key to disassemble the BBU. Does anyone know how big the allen screw is? I'm referring to the one under the rear sight. Is it 0.89mm (guessing from this)

I'm also considering converting to a metal slide but in addition to it appearing to be a big pain in the ass, I've heard of problems after the conversion is done (semi-auto not functioning, cycling problems etc.). If someone could suggest a list of items I need to successfully convert to a metal slide (in addition to the slide that is :p), that'd be great.

Thanks in advance!

yes it is a .9mm key

Thanks for that. I'll have to go and get a better set of allen keys.

I know how to replace the slide but I was wondering if I need to upgrade other parts to increase gas flow, improve gas consumption etc. I'd imagine more gas is needed to cycle the metal slide.
