Apples and oranges comparison. Polymer striker fired, DAO hammer fired with steel frame and slide. 4046 is a boat anchor and not in production anymore, the M&P is. Mags are getting pricey for the 40XX series guns.

I've bought two 4046s for under $300, I'd buy another at that price if I could. I have no interest in the M&P series.

Hope this helps
