I am working on my draw of my Remington 1911r1 from a concealed holster. When trying to rapid draw, the front sight which is very squared and blocky, drags and hangs in the holster slowing my draw time severely. I can't get it to clear the slide hostler good enough half the time. This holster is not rock solid and moves slightly when drawing, plus it is not reinforced so it collapses when drawing. Any suggestions? Is this a technique issue, holster problem or a front sight problem?
