That was NYPD request (8 lb) and NY2 (12 lb) that was the doing of NYPD and they did the 12 lb NY2They also started offering aftermarket heavy drop-in trigger springs to address that problem. I served as a local police reserve when that was happening, and when we got our duty guns (reserves had to buy them ourselves) we were given the new spring kits on qualification day and had to put them in ourselves before we qualified. Fun times!! I think my G22 ended up with a 12lb trigger... if I remember correctly. It was brutal, but no more "Glock legs" ever again.
They didn’t even authorize autos for standard coppers til around 1994/5 and it was Glock NY2 Sig DAO (not DAK) and S&W DAO 5946 (my agency had some and the 5946 had the smoothest shortest DA trigger stroke very underrated and was like a very tuned and slicked up PPC revolver but shorter trigger travel)
Between 2016 and 2019 NYPD ran a test that half the recruits had the standard 5 lb trigger the others the NY trigger and the scores went up.
Maryland (if I remember right from Glock Armorer course back them) had the same results
NYPD ran the 12 lb to better emulate a revolver but it didn’t help as one rookie still accidentally shot a subject and went to prison bottom line don’t point guns at people uiu have no probable Cause or are legal to shoot
A retired NYPD friend I met at East Coast Revolver Roundup works as rangemaster in his retired job and said they had a test of 100 FN 509 MRD (what LaPD use now) with red dot as a test. And it got approved just waiting on downtown to write up the approval letter.
The best way to get a revolver trigger on a Glock is run the 8 lb with a minus connector
