while it is not really a concealed ,Look at the Fobus.I use one with my full size Kimber.Only about $20.00 You can leave your shirt tail out.Only draw back is that they are also plastic and can wear the finish off pretty quickly.Don't matter to me though I use mine as a tool and don't mind a few slick spots.
Gun comes out quick and gets in to position .At first you wouldn't think it will hold one good enough but when it "clicks " in it is there.That might be an option untill you get what you want.When you get you "Real holster remember comfort,comfort ,comfort.If you wear it for long periods of time that is a requirement.Just a thought bud...........Alton
