Why are 14" barrel shotguns so common?
It seems most manufactures make a 14" barrel shotgun for police/
A remington could easily be done at 12" and I think a Benelli could go to 12" a mossberg could go to 13" all of these can be done with a standard magazine tube.
So why 14"? I looked up vellocities and the velocity difference between a 14" barrel and a 12 barrel is less than 20 fps.
If you want a vision of the future, imagine a boot stamping on a human face - forever.
