Has anyone used MMC night sights on a Kahr pistol? I am specifically looking at green front with blue dots in the rear. If you have seen the blue rears, is the contrast different enough to make the green front pop out. A good part of my work day is spent under red lights, so red, yellow, or orange rears do not work and I do not like the three green dots on my M&P40c.

Other suggestions for nights sights are welcome as well. I am waiting for CT grips with green diodes, but do not see them coming out soon enough to fill my needs.
