@Taro: Uggg, I have seen a couple broken mags and I'm not sure I want to deal with the prospect of a mile of loose spring coil...
@Styrak: I think I'd buy me a Magpul Masada before going with the G&G Sig.
@Kozzie: Yes, I saw a Youtube video where they compared TM vs ICS gearboxes, and everything but the nozzle and hammer were the same. The TM plunger had holes in it and the ICS nozzle was longer.
So in summary, does anyone sell mid or lo cap mags for ICS Sigs?
