I am not certain that the cops were entirely at fault for this one. You see, their issue weapons have 13 lb triggers - that is, it takes 13 pounds of pressure to get the trigger to work. It is hard to make accurate shots when you have to fight your weapon to get every round off.
I do, however, blame NYPD’s policies and training. They’ve had notoriously atrocious firearms training/conduct policies for literally decades; the 13lb triggers were their ‘answer’ to keeping their officers from shooting each other with their then-new Glock pistols. Not better initial training, not better transition training, not discipline for screwing around with your sidearm in the squad room, not remedial training. A heavier trigger. Yeah, okay, that’s going to solve the problem. Not.
Before someone blames the Glocks, keep in mind that in the 1970s and 1980s, before the Glocks were adopted, the NYPD issued double action revolvers. And the officer ‘accidental discharge’ rate was about the same even with those.
13# triggers? Haven’t heard of that.
They should standardize on Kimbers. Best triggers evuh and allow you stay on target.
