For a few years in Florida I carried a S&W 2 1/2" model 66 in an inside waist holster. I carried in the appendix position. It wasn't the most comfortable for sitting, but there are much better options for IWB holsters these days. I usually wore an undershirt and a Guayabera shirt. By lifting the shirt with the off-hand, drawing the revolver with the strong hand and bringing the off-hand into gripping position, it was a very quick draw. If I had to do it over again, I'd have removed the hammer spur, as I always shoot double-action. I never had a snag upon drawing, but the hammer spur would wear a hole in the undershirt after some time.
