My State Police agency, from which I am now greatfully retired< went from Glock 17s(with a bunch of AD's and lawsuits) to the Sig P220 45, which we all loved and No ADs, back to a Glock 22(becuase our cop/military groupy political suck-up administrator, who BTW held Glock stock, said our Agts 'needed' more bullets. Thankfully, due our efforts in training/range time/tactical/Simunitions drills, the ADs didn't come back like the G17 era. As one of the Fire Arms staff I worked hard on that and got a policy approved to allow Agts to carry 1911s plus other approved weapons with standards higher than issue weapons. Reason for 9mm rejection-shootout with 2 Agts & Deputy VS 1 bad guy-19! 9mm hits with Fed 147 Hydra-Shok-0 stops/1 G21 45 w/ WW Black Talon from deputy+suspect down.
