One of my instructors was invited to a party in Marana, suspect in a cotton field shooting with a rifle. Rifle was a .30-06, officers had their .40s and one shotgun with buckshot. One of the officers hit the suspect at 110 yards with his .40 pistol.
After that, my friend started carrying slugs in his shotgun.
Same dept was just out doing annual quals. 25 officers. On "patrol carbine" (M4-geries), 3 qualified on the first try. Dude copped an attitude when I said "You know, we do after work tutoring if any of your officers are interested."
