I have a red dot scope on one of my .40 cal. HiPoint carbines, the other has iron sights. I also have a red dot on my Smith .22. but open sights on my Mark II Ruger. Both 320's have Advantage Tactical sights that seem to work better for me.
From what I've seen, competition wise, only the more expensive holografic (sp) battery powered sights are suitable on competition pistols, meaning more compact, lighter, and better able to take the recoil of the slide.
I don't shoot competition, I wish that I could but I can't move fast and get into all kinds of pretzel positions.

I believe, after all these years, I'm comfortable with sight picture and recoil but would lose points for being too slow.
Again, excellent choice!
