Poorly designed gun
I bought this M&P 9 Shield and tested it carefully. I have more than 6 decades of shooting experience and I must tell you that this pistol is very badly designed. The slide is well too hard to move and the trigger is very hard also. Capacity is also not so good. In real shooting at 7 yards distance, I got an average 91 score from 10 shots with a Sig Sauer 2022, Glock 17 gen4, Ruger LC9S, and a couple of other pistols. However, with this Shield, I got zero or 1 in several shootings. Now I replaced the trigger and it makes the pistol better but, anyway, it is still hard to use. It was replaced with Glock 43X and now I am happy. I know Smith and Wesson for many decades and I did not expect so bad work from them. Big stigma on this company. I never will buy anything from S&W.
