I have - er had, before my tragic boating accident, a Rossi Circuit Judge that shot both .45 Colt Long cartridge AND 410 shotgun shells
It was a rifle built like a 5-shot revolver
I doubt not that there are individuals in the LEO profession who carry a .45 Colt by personal choice, but I was referring to an agency that issues them to all personnel and purchases that ammo for the entire department.
I don’t thing you will find one.
I own two myself, and ALWAYS carry one or the other when I am not in the city.
When in the city where things happen at arm’s length, I prefer a snub nose.
Quicker.
