Although the Dawson sights look great, I shoot my son M&P with tall sights very well. I find them a very well fit on his 4" 10mm. Not to knock the M&P but my Rock Island Ultra FSHC shoots circles around the M&P, way more accurate and target re acquisition is much better for shot times. I also shoot hot loads of 1250 to 1300FPS with 180 to 200gn bullets, no worries about blowing up the pistol. Plus it comes with a lot of factory upgrades for the $$$. Way more gun for the money. If you think you need to carry a 10 for self defense you need to work on shot placement. I carry a Shield Gen 1 in .40 with hand loaded to almost 40 major hollow point ammo, and it will do more damage than any 9mm round. 9mm velocity with .40 thump.
