We have 14" M870Ps that we'll likely keep around for the foreseeable future as we issue them to LEOs from other agencies when they help us on protection details, as they're not qual'd on the Colt SMG.
There is some pretty serious hatred against them, which is a shame as they're a good tool. I can't blame people for not wanting to touch them with a 10 foot pole, though......the duty load is a Winchester Ranger 00 buck which has a horrible pattern that can barely keep pellets on a human torso at 15 yards. The LOP is also incredibly long and makes it very unwieldy and uncomfortable.
If we went to Federal Flight Control and used a shorter LOP stock, I wonder if people might feel differently.
