Scrapple,

Welcome aboard. That is a nice looking Glock in your link to that website. Having played with Red Dots atop revolvers and Semi's, I concur the lower the better. This is one of the reasons I like the JPoint. It has a notch in the back of the sight that can sorta be used as a rear iron. It will not co-witness in any way, but when you snap the gun up and look for the rear notch, the dot is not far away. Not nearly as nice as the one in picture, though.
