A customizable firearm is disclosed. The firearm can perform one or more functions, including firing a bullet, firing a less-than-lethal projectile, and/or providing light. In some cases, the firearm includes a main frame component having an inner cavity, wherein a barrel is slidably received within the cavity so as to selectively slide back and forth within the cavity. In some cases, a proximal end of the barrel comprises a bullet chamber. In such cases, the barrel fires the bullet by carrying the bullet proximally and striking it against a stationary firing pin. In other cases, a firing pin is attached to a distal end of the barrel. In such cases, the barrel discharges the firearm by moving the firing pin distally and striking a cartridge at a distal end of the main frame. In some cases, the barrel rotates between a safe and a fire alignment. Other implementations are described.
