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.
Again, an inordinate amount of those are sold to law enforcement and government agencies for their on and off-duty firearms.
It's far less costly for agencies to replace firearms instead of rebuilding them. No need to hire and outfit an armorer or incur legal liability from servicing the weapons. Additionally, these type of guns are not designed to be rebuilt as older firearms were. It's a $400 disposable tool to them. The days of being issued a .38 revolver, firing twelve rounds once a year on the range to remain certified, and then turning your gun in when retiring decades later are long gone.
Between new hires and training, most departments are ordering all new handguns less than every ten years. A quick calculation of departments and agencies all over the country shows just how many of these weapons regularly sold are for law enforcement, government agencies, and private security.
The 40 S&W for law enforcement and government agencies is another example of caliber and model changes that affect sales data. It was introduced in 1990, departments switched to it, and by 2015 departments were switching back to 9mm. During that time, many individuals bought personal handguns in 40 S&W following the trend and seeking ammunition that was lowered in price due to the increased implementation. Since the military adopted the Sig P320-M17 in 2017, many departments and agencies are also adopting them as they can get a good price.
All the training in the world and the best holster available isn't going to help you when an incompetent individual handles your gun. You spend every effort, constantly throughout your day, ensuring that you're the only one who will handle your gun and that you'll keep it out of the hands of children and untrained adults. Then you get pulled over by the cops...
...and you're completely at the mercy of their deficiencies in mindset, training, and focus. A manual safety in this case would have been for her, not him. None of his training and care has any offset for her incompetence.
The world has changed. A gun carrier is forewarned that the chances of a shockingly incompetent cop handling their weapon on their person is increasing, not decreasing.
