Rastoff,

Interesting post today on 3 dot sights inquiring the same issue on the stock 3 dot sights on M & P models.

I have looked at some of my other handguns with 3 dot sights and most all of them, there will be a different poi depending if you sight by the 3 dots or conventional sighting method lining up front post at top of the notch.
