A while ago I wrote an short article about converting my TM Glock 26 to full auto...

While the apparent outcome is that it doesn't work on Marui's Glock, the concept, I believe, is rather the same. (That is, if KSC's semi-auto Glocks have the same internal system as TM's 26).
Anyways, hope this helps in some way.
