In any incidents where rounds are fired, anybody involved usually has their firearms secured by forensics personal and gone over with a fine tooth comb to determine which weapons were fired and matching them to ballistic evidence found on scene or if anything internally has been modified outside of standard issue req’s so that opposing attorneys during any following trial or invest. can’t turn that around and say “Hey Off Joe Blow had replaced his standard 12lb trigger with a modified trigger that only has a 4.5lb pull. This guy is a loose canon who was just looking to get into a gunfight and as such even modified his issued dept firearm with a custom gunfighting trigger!” The case would be shot right there, bad guy gets off and the cop would be hung out to dry, just for wanting a non shit brick sandy beach trigger.
Cheer up: nowadays the perp gets compassionate release because of Teh Covid,
and will never return to appear at trial anyhow. So polish that sear, bay-bay!
20,000 round endurance test.
Is that just stupid or is it me???
First - no cop issued this gun is EVER going to run 20,000 rounds through it. Not 10% of that. At least not on a single weapon.
(As
@weekendracer alludes
above), you don't measure the lifetime of a light bulb
to see if it meets a "400 day bulb" advertising campaign, by leaving one bulb turned on
for more than a year and not starting the production line until you see if it survives.
You test a bunch of bulbs and extrapolate the expected reliability
from how much infant mortality you see in the sample.
Similarly, you don't wait to see how long a gun lasts in service
to predict its reliability - you beat the snot out of some and see if
any common fatal design flaws surface. That's usually how systems exhibit failure.
Note the 6000-round tests of the 1911:
The adoption of the M1911 came to be through a lengthy trials process and a partnership between Colt’s Mfg. and John Moses Browning.

It
seems like over 1.2 millions rounds were fired
when evaluating the M16:
Report of the M16 Rifle Review Panel
Second - how many guns did they do? I'm betting one. So you're entire Go/NoGo is based on as single sample. Don't take 10 of them and run 10,000 rounds. Do one at 20,000. Possibly hand-picked by the manufacturer.
If I were an armorer, I'd go down to Joe Blow Gunshop and buy 5 of them (because I doubt my department would spring for 10) and then run THEM thru 10,000 rounds as fast as I actually could.
THAT'S a test.
MTBF estimation is such a formal affair that an industrial Special Interest Group
has dinner every month just to discuss stuff like that. It's one of The Bride's specialties.
There's no lack of engineering consultants that a police department can hire to design
a testing program - if they want to do it right.
If they didn't test it right, it was probably because The Fix Was In.
It’s a very awkward transition, or at least has been from my experience. I’m currently trying to adjust myself to my first RDS on a G45. I’m literally just presenting the weapon over and over and over, watching tv, present the pistol and try to have the Dot on whatever is deemed the threat in each particular room. Walking around the house, present, etc etc and I’m still struggling to find the dot instinctively.
Put a laser on it, and get a cat?
Belay that;
never mind.
I know what the advantage is myself having run the things on pins etcetera but I also simultaneously groan going "oh great more s*** to put batteries in" .
Don't get your bowels in an uproar.
I remember when bicycle headlight technology
was so primitive that the New Hotness was
quartz bulbs and a NiCad that fit in a water bottle cage
that cost well over $100.
Hell, I remember the Aluma-Weld/Gorilla-Tape/Alinco-Magnet
guy at the Flea@MIT proving to me with actual geometric logic
that it was mathematically impossible
to focus the light beam coming from an LED.
Now almost any cheezoid flashlight from Harbor Freight
has vastly superior performance off of standard LEDs
and a few crap AAA alkalines.
Component and power reliability and longevity
are careening towards good plateaus.
It's getting so that operating operators deservedly reject electronic
sights that don't use batteries available at
every supermarket
checkout impulse buy rack.
(Unless you accidentally buy a pirate knock-off assembled
in some goober's Wuhan apartment living room.
Then you won't be so happy).
