Shotguns: Let it. Go.
For my entire police career, I've been fielding Remington Model 870 shotguns. I know how to operate them, and have by choice gone hunting with them, to great success. I'm moderately okay with them on the trap and skeet ranges. I respect the 870, and have chosen it over other pump shotguns in the past.
Can we get over the pump shotgun, for police patrol work? Or at least create a double-action pump gun, in which the first shot is pumped, and the rest are semi-auto?
The last time that I pulled out a pump shotgun on a guy, I found myself broadcasting orders to the (himself shotgun-armed) actor over my patrol car's public address system, while pointing my temporarily-single-shot shotgun at the actor and speaking into the microphone in my hand.
I have said it before, and I will say it again: The day of the pump shotgun in patrol should be over.
There are ample quality semi-auto shotguns out there.
