I'm wanting a OWB rig for my 1911's and was considering a Null Gibraltar speed scabbard,Kramer belt scabbard or a galco concealable. which of these is the most stable and highest riding? I've carried alot in owb rigs but mostly a 3 1/2" 1911 or snub nose revolver nothing longer than that. So for those here that carry owb can it be hidden with only a t shirt or polo type shirt,i.e. with out wearing 2 shirts?
