Yep. Who knows how many negligent discharges were prevented by the heavier trigger. Look up the Peter Liang shooting. Rookie cop doing a vertical patrol in a housing project stairwell. Had his gun out (as I did many times in that very project). Killed a guy y letting a shot go when he was startled by a door opening. Stated the gun went off accidentally. At his trial, the jury was able to handle his Glock and pull the trigger. They stated there was no way the gun went off without a deliberate pull. No reason at all for a duty weapon to have that light a pull. They could have compromised and went to an 8 or 9 pound trigger if they really felt the need.
When we went to the 9MM, the anti-cop people went nuts, so the mayor compromised with 10 round mags. Next mayor immediately rectified that and went to 15 round mags. We were supposed to qualify 4 times a year. Within three months it was 3 times, and within another 3 months it was the same twice a year we did with the revolver. They skimp on training as much as they can. We went from a 15 round mag of the simunition paintball ammo for one training cycle. Used to be called InTac, for In Service Tactical training. Within 3 months it was 5 rounds. Three months later it was 3 rounds, and the new scenarios had fewer and fewer times shooting was even necessary. The actors would give up at the first command or drop their gun altogether when the cops walked up.
