Question to the Home Office:

To ask the Secretary of State for the Home Department, with reference to the UK2: Preliminary market engagement notice, 2026/S 000-050599 published on 29 May 2026, what firearms does the Metropolitan Police Service hold chambered in .300BLK.

The Home Office does not hold information on the specific firearms and ammunition held by the Metropolitan Police Service. Decisions about the types of firearms and ammunition used by police forces are operational matters for forces’ chief officers.

Chief officer procurement decisions are informed by operational requirements and individual forces’ strategic threat and risk assessments.
