Duty Arms Index

Holosun 407K vs Holosun EPS

Maker specs with sources and which agencies in the index issue each.

Data coverage: Adoption is based on 105 agencies in the Duty Arms Index with a current, sourced pistol optic entry; SWAT / tactical-unit entries are not counted. 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. These counts cover US agencies only; agencies outside the US are not included here (see agencies by country). Data last updated Oct 11, 2026.

Print evaluation memo

Values are copied exactly as each maker publishes them, with a numbered source for each; we don't test, convert units or rate anything. “Not published” means the maker's current spec page or manual doesn't list it. Columns are in order of agency count in the index, not preference. Shaded rows differ.
