What guns do federal agents carry?

Short answer: most federal agents carry a Glock (87% of duty pistols). The Glock G19 is the most common primary duty pistol (8 of 22 agencies, 36.4%), ahead of the Glock G19M (5), and 95.5% of duty pistols are 9mm. For every agency's current loadout, see the federal agency list.

Data coverage: Based on 27 federal agencies in the Duty Arms Index with a current, sourced pistol, rifle or shotgun entry: 22 with a primary duty pistol, 7 with a patrol rifle and 2 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. Data last updated Oct 10, 2026.
