The New York Trigger is not an option. It's mandated for any NYPD duty gun. It's a 12-pound trigger pull instead of the usual 5.5 pound Glock pull, which might explain some of the NYPD's lousy marksmanship.
Mandated for NYPD, optional for many other buyers.
Police marksmanship has two issues. First is that many officers get little or no practice in shooting, other than annual or semi-annual qualifications. Second is that, when under fire, few people have very good marksmanship.
NYPD is on the average with most other agencies, including FBI and the US Marshals, for accuracy in firefights. Statistically, it's no worse than civilians shooting under similar circumstances. Unfortunately, in NYC, there are a lot of non-target people that can be hit.
There are quite a few debates about the effectiveness of the heavy trigger pull, both on accuracy under fire as well as whether or not is provides the safety mechanism it's designed to do, preventing negligent discharges. Even the NYPD firearms trainers have varied opinions.
But at least the top brass can say they did something.
