I have a 9mm Shield Plus. Its out now at a shop getting milled for a Holosun 507K-X2 (which has a small footprint). I also have an M&P 5" Pro with a Holosun 507C-X2 (large footprint).
Have had the Holosun on the full size for a while & I like it.
OK, at least going by the illustration and features at the S&W website......
Those iron sights don't appear to be high enough to work with an optic. Yes, you need usable iron sights, unless your pistol is a range toy only.
Did you receive mounting plates with the gun? If not, what bolt/screw hole pattern to you have? This will dictate what sights you can use. Also, the optic is going to add considerable bulk to your firearm. This may present issues in trying to conceal it. Depending upon how wide your slide is, this will also narrow the choice.
Hopefully someone who's tried it will chip in.

If you may be using this for defensive purposes, I hope that you practice enough that you always manage to have the dot in your field of view when you snap the gun up on target. And that your faith in the red dot being 100% functional and visible isn't misplaced. I'm not that trusting.
