Funny I was just practicing this last night, quick draw aim to a point and dry fire, then try to hold steady and see where the sights are. I have to say I was impressed at just how close my aim was. I'm using a mini 1911 and it points naturally, like others have said this may be a bit of a struggle with the Glock grip angle. That is why I carry what I do, because it is such a natural point for me. It takes little to no adjustment on the sights after just pointing either one or two handed. Keep practicing it will come, or consider something with a more natural point for you and it should be much easier. JMHO. Good luck!
