That's misleading because most of those sales are to law enforcement and private security for both their on and off duty handguns.
Respectfully, I would disagree, The private market dwarfs the LE market. These “unsafe” triggers are everywhere in civilian targeted platforms. Everything from pocket pistols to high end sigs. There are many times more pistols with Glock style triggers sold every year than pistols with safeties or revolvers. It’s not even close and it’s civilians driving it. If you look at the majority of respected firearms experts they are not calling this design inherently unsafe. Like every gun, they simply need to be handled correctly.
In every instance ( except dropped sig p320’s) these are negligent (not accidental) discharges. Somebody pressed the trigger hard enough to discharge the firearm as intended. If you look at the amount of negligent discharges compared to the millions sold/carried etc. the number is actually quite low. The media loves to hype anything that makes gun ownership and carrying look bad. There is not an epidemic of Glock triggers wounding people. Quite the opposite.
