Firearm (Statutory Definition)

Definition

A lethal barrelled weapon from which any shot, bullet, or other missile can be discharged. Each jurisdiction sets its own definition; the Indian Arms Act, the US Gun Control Act, and the UK Firearms Act 1968 each enumerate features that bring an item within or outside the statutory category. The examiner must apply the relevant definition, not colloquial usage.

Common questions

Why do statutory and colloquial definitions of firearm diverge?+

Colloquial usage often includes replicas, deactivated weapons, or air guns that look and function like firearms but fall outside a jurisdiction's statutory wording. An examiner who applies everyday intuition instead of the operative text risks misclassifying an item for court purposes.

What happens when an item sits at the edge of the definition?+

The examiner tests the item against the specific statutory criteria, such as barrel length, calibre, or whether it can be readily converted to discharge a missile, and documents which criteria are met rather than offering a general opinion on whether it looks like a gun.
