I have a LH Comp Tac C.T.A.C. for a 1911 slider, it is actually IWB. I use that when I can not pocket carry. I keep it at about 5 oclock, with a left hand cant I just put the back of my hand against my back and find the grips. I tried it with a RH cant but it feels awkward cocking my hand at that angle to draw. In work clothes I pocket carry. The slider is good if you plan on getting a Full Size 1911 it is made to hadle all barrel lengths.
