Has the M&P 2.0 been tested or adopted by any police departments for duty use? I am only asking because I generally don't purchase handguns unless they have been tested by a military or police agency.
These models are ones that I can think of that have been extensively tested both in the US and abroad, and adopted extensively for police or military usage in the US and abroad:
Beretta M9 or 92FS, PX4
Browning High Power, also called the FN GP35
Colt 1911
CZ75B
Glocks in most calibers and models
HK VP70, HK P9S, P7, P7 M8, USP, P8, P10, P2000, HK45, P30, VP9, etc.
Manurhin MR73
Ruger GP100, P89, P90
SIG P210, also known as Swiss Arms P210 or SIG P49
SIG Sauer P220, also called P75 or Browning BDA
SIG Sauer P225, also called P6
SIG Sauer P226, also called MK 25
SIG Sauer 228, also called M11
SIG Sauer P229
SIG Sauer P2022, also called SIG Pro, or SIG 2009
SIG P320, also called M17 or M18, depending on frame and slide size fitted
S&W Autos and Revolvers of almost any model in the currently popular defense calibers
Walther PP, PPK, PPK/S, P38, P1, P4, P5, P99, P99Q, PPQ, PPQ M1, PPQ M2, the newest PPQ M3.
Honestly, if you cannot find one that meets your needs in the above list of extensively tested, and widely adopted pistols, then you are too picky.
