Gas mag compatibility, please add.

[simon]

Wanted to buy a gas mag for your pistol but weren't sure if the make was compatible with your gun? Me too, so I'm starting this thread to try and get a list of what is and is not, to help me and others. If you know for a fact please add a reply.

To start things off I have a HFC Glock 18C and a KSC Glock 18C and both makes of mags work in both guns.

I also have a TM 4.3 Hi-capa and TM 5.1 mags work in this tho they do stick out the bottom slightly.
