From my reading it seems that they should work. For many they are fine as-is BUT you should check fitment of the front screw as it may need to be filed or sanded down slightly so that it tightens down and doesn't rub the barrel. Really not that difficult to do. I have the tfo sights on my g17 and like them. It seems that glock sight channels are all sane and main variances are in the height of the sights and thus retaining screw per model... not the dovetail. Here is a similar conversation but you may still want to contact tru glo... https://www.glocktalk.com/threads/truglo-not-for-g36-or-g30s.1529863/
Christopher the G30S essentially has the same slide as the G36. To get the right sights 1st time, I would ask Truglo for their fit recommendation directly via email inquiry at : http://www.truglo.com/contact_us.asp
