Add adjustable sight to a S&W 910?

[b.thomas]

My 910 shoots a little to the left and I really like the idea of adjustable sights even on a just-for-fun target gun.
Two sights I'm looking at are:

#1. TPU91SW REAR SIGHT (only replacing the rear sight)

#2. millet SERIES 100:

*anyone have suggestions or experience with either one or the other and/or which would be preferred?
also a good source?

I seen one pic of that model and it appears to be windage adjustable. Tap sight in the direction you want to move the POI IIRC. Dovetail mounted sights just need a different type of persuasion than screw adjusted types...
