Heckler & Koch USP pistols are prominent in the Episode 0 movie, both in the hands of ex-JGSDF officer and Bettenou user Makiro Serada and Public Security Force operators when they are still contractors as their main sidearm.
A SIG-Sauer P232 was used by a Security Police officer in "Murder at the Ball" before she was killed. Public Prosecutor Office agents sent to the Sasa estate in "House, Unmasked" use P232s as their main sidearms. Shinjuro and Inga criticize them for carrying firearms, which is correct since actual Public Prosecutor employees, regardless of their status, are not lawfully allowed by the Ministry of Justice to be armed. However, this may be due to the fact that in the Un-Go world, Japan had just been through a major war with several terrorist attacks that the MOJ had allowed all law enforcement personnel including Public Prosecutor employees to have pistols with them for protection in light of another terrorist attack.

The New Nambu Model 60 is used by Japanese police officers, notably officers from the Tokyo Metropolitan Police Department as their main sidearm. In reality, they use the Model 60 as one of the main sidearms approved for use by the MPD aside from the Smith & Wesson Model 37.
