Regarding that statistic. Is that a case of selecting a slug after rounds are already being fired? Or is that including an officer arriving with a tube full of buckshot then determining that the threat may be in a vehicle? If time permits, loading a slug when a slug would be better as you prepare the SG for the engagement would be prudent. Stuffing a slug into the tube from the side saddle before charging the gun may make some sense. This kind of decision on arrival seems reasonable. I have heard @jlw mention that he used to roll/currently rolls with two like SG. One with buck and one with slug so that the most appropriate load can be selected upon arrival.
