Data coverage: Based on 20 Michigan agencies in the Duty Arms Index with a current, sourced pistol, rifle or shotgun entry: 15 with a primary duty pistol, 4 with a patrol rifle and 3 with a duty shotgun (SWAT/tactical-unit guns and 1033 military-surplus rifles excluded). Agencies that authorize several primaries count once for each. Counts include only current entries with a public source; agencies not yet in the index, or without a sourced entry for this item, are not counted, so treat shares as a picture of the Duty Arms Index, not of every agency.
