I don’t recall hearing about this type of incident back when cops carried revolvers, Barney Fife types notwithstanding.
One of my neighbors in New Mexico had a Colt single action .45 revolver that his dad carried as a Sandoval County Sheriff’s deputy.
Oh no! I hope he got rid of it.
Surrounded by fully auto weapons and mines, M*A*S*H decided to do an anti-gun screed about a single action Colt 45.
Most of the departments in NM now have weapon standardization, so it’s a dull collection of mag-dump capable plastic fantastics. When I first moved here cops pretty much could carry anything they could qualify with. Met one who had a nickel plated 1911 in .38 Super.
