How big is the Raven Concealment Eidolon compared to other AIWB holsters?

I'm new to conceal carrying so the Eidolon is the only IWB holster I have ever tried/owned but I saw a comment on this sub saying the Eidolon is a huge hoslter for appendix carry. Is it really that much bigger than other quality AIWB holsters? via /r/CCW http://ift.tt/2jKXwVx
