Advice - Dawson sights on M&P 45 4 inch

[ranger]

I purchased some used Dawson M&P fixed rear sights and fiber optic fronts recently. I want to install a set of these on my S&W M&P 45 4 inch pistol. Does anyone have experience with these sights on a 4 inch 45 - specifically, which height front sight? I will ask Dawson also but wanted to see if anyone had experience here.

Thanks

i like Dawson sights but on my 45 i could not get the combo right for it (me), even with shortest front sight should went ahead and bought the adjustable like my all my other M & P's.

i want by round to hit right on top of the front sight so my sight never covers the target. like on a head shot or a plate at 25 yards.
