after 28 years as a LEO (city,county,state,Army MP officer & as a SDUSM) i cannot recall EVER seeing anyone with a 14" barreled shotgun, with the exception of DUSM's moving prisoners to a place of detention/confinement. (the so-called "witness protection" Model 870 Remington is a hand-FULL & is about as UNpleasant on one end as the other!!!)
18" or 20" inch barrels are the rule, when i comes to RIOT GUNS.
make mine an Ithaca Featherweight Model 37 pump-gun, with 20" barrel (loaded with 2 3/4" short magnum,#1 Buck) & 8 shot mag!!!
