Yes, the holster pictured is really made for one special purpose with is to keep the Ruger LCP from “patterning” when carried in the back pocket of a pair of jeans. It certainly works well for that. When carried, it looks exactly like a wallet. You can imagine the surprise of a knife wielding crook when he says “give me your wallet, now!”.
I can certainly see that it’s a beautiful tool for the purpose it was made. Certainly would be a heck of a surprise for would -be thief! With that exposed trigger I would think you’d want to practice your holster work darn near every day though and have that muscle memory well in place.
