In 2020, the United States, the United Kingdom, and the European Union, placed restrictions on the sale of police and military equipment to Hong Kong following the passing of the national security law. As a consequence, the HKPF — who are seeking to replace its decades-old Model 10 revolvers and MP5 submachine guns — are searching for suppliers elsewhere. In testing of MP5 replacements, the HKPF has expressed disappointment with the reliability of firearms from China and the ergonomics of those from Russia.
