I sold my first M&P Shield 9mm because I couldn't get two rounds within 5-6 inches of each other. That's at 3 yards with stock sights and then HiViz sights installed and adjusted several times to sight it in.
Fast forward to today when I took my new M&P Shield 9mm to the range and that thing is more accurate than my M&P 9 full size or any of my Glocks or Sigs.
The only mod this one will see are the Talon grips I put on it.
At 3, 7 and 15 yards it is POA/POI precise. It made me feel like I was better at shooting than I ever thought I was. Ran out of ammo so I only got to put 300 rounds down range. Not paying $20.00 for 50 rds. at the range. lol
Now I need 1 in .40 and .45. Possibly Performance Center models.
