In practice

Offences under s.5(1)(a), (ab), (aba), (ac), (ad), (ae), (af), (ag), (ba) or (c) and s.5(1A)(a) are indictable-only and must be tried at the Crown Court; those under s.5(1)(b) and s.5(1A)(b) to (g) are either-way and may be tried at the magistrates' court or the Crown Court. Firearms must be made safe by a trained officer before being handled. Continuity of the exhibit from scene to storage is essential. Check the National Firearms Licensing Management System for any certificates or previous incidents. The suspect must be cautioned in accordance with Code C PACE 1984 before any questions about the offence are put to them. Interviews must be audio-recorded (Code E) and may be visually recorded (Code F).
