As I understand it, NHC will cut the dovetails on other brands if they feel its safe to do so (enough material on top of slide). Then you must purchase whichever plate(s) you need, options are limited. As for as installing the plates, they work as advertised. Took me less than three minutes to swap from open sight to red dot, including mounting the red dot on the plate.
I think the Nighthawk IOS system is fantastic. The design, machine work, fitment is excellent. Don't own one as yet. Basically because the plates they make only work with a very limited number of red dot brands. I had been hoping they would expand the plate selection but it hasn't happened to the best of my knowledge.
