Holster claws at 4-5 o'clock

I've been shopping around for my first holster (yes, I have seen the FAQ link) and was wondering if claws, like the RCS claw or T.Rex Arms raptor claw can work for 4-5 o'clock IWB or if they are only intended for AIWB. Seems like the potential for reduction in grip printing would work work just as well in 4-5 o'clock as AIWB, unless I'm missing something anyway.Also, is cant purely for concealment or is it primarily for ease of draw? I've tested concealing my G-19 by shoving it in my waistband (unchambered, just walking around the house) and there's abysmal printing, but it seems like a cant would increase draw speed slightly. I'm considering a T.Rex Arms Raptor, but it doesn't seem to have adjustable cant. via /r/CCW http://ift.tt/2oyUG6Z
