I had a Burris Fast Fire mounted in the rear sight dove tail on my 17c, but found it moved too much for my liking. My current set up is a Carver mount and a Cmore. I appreciate the weight but it seems that the height difference between my iron sights and the dot are causing me a problem; so much so that I rarely shoot the dot gun in unlimited. I am contemplating a smaller sight milled into the slide so that it rides lower, basically cowitnessing with my iron sights (or closely cowitnessing). Am I thinking correctly?
