Yea it looks like it would just mount on there. I just wanted to completely cover the holes on top of the slide using a smaller footprint optic. A plate from my S&W M&P 2.0 10MM will fit if I shave a bit off the forward side. I may just use the sealing plate for a Trijicon RMR that has the corners cut out to allow the pegs of the optic plate to protrude and engage the forward sight base holes.
