We're lucky. We carry three long guns in our patrol vehicles at all times. Remington 11-87 12 gauge w/ 00 buck, Ruger 9mm Carbine rifles (we carry Ruger P-89s (sidearm) on duty so mags are interchangeable), and M-4s. We're pretty much prepared for any type of situation that may arise. Qualifying with all these weapons is an all day affair though, but well worth it.
