Compare pistol optics

Slide-mounted red dots compared on the maker's own published specs (footprint, emitter, dot, battery and stated life), with the number of agencies in the index that issue each and the pistols they sit on. Values are copied as published, with a source and access date for each; missing values say “Not published”. How we compile specs.

Data coverage: 22 pistol optics with a maker spec sheet. Adoption is based on 105 agencies in the Duty Arms Index with a current, sourced pistol optic entry on a duty pistol; 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.

Common comparisons

Numbers are agencies in the index issuing each. Pairs are picked for search interest and adoption, not as a judgement.

Sorted by agencies in the index, then A–Z. “Fields published” counts how many of our 17 spec fields the maker publishes; it is not a score.
