I have been scouring the internet for a holster that will let me OC comfortably, but I have not found one that will accomodate the gargantuan accessory rail. It is a full size 1911 and the holster/belt I have really kill my back when I have to carry for work and when I am out and about. Anyone know of a company that make one? I should also add that having it be a retention holster would be even better.
