👉 A backup weapon, also known as an alternative weapon or secondary weapon, is a firearm that a user carries alongside their primary weapon for additional protection or tactical flexibility. This secondary weapon is typically designed to be used in situations where the primary weapon might not be optimal or when the user needs to engage targets from a distance or in close-quarters combat. It can be a pistol, shotgun, or even a non-firearm weapon like a baton, providing the user with options to adapt to varying combat scenarios and ensuring they are better prepared for any potential threats.
