Duty Arms IndexStreamlight TLR-7 X vs SureFire X300 Ultra (X300U)
Data coverage: Adoption is based on 50 agencies in the Duty Arms Index with a current, sourced weapon light 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.
