👉 The fellow weapon, often referred to as the "companion" or "sidearm," is a secondary firearm typically carried by military personnel, law enforcement officers, and other armed individuals. It usually shares a common design with the primary weapon, such as a pistol or rifle, but may have distinct features like a shorter barrel, a different magazine capacity, or a more compact form factor. The companion weapon serves to extend the operational range and versatility of the primary firearm, allowing users to engage targets from a safer distance or in situations where the primary weapon might be impractical. It's essential for tactical flexibility and can include variations like shotguns, submachine guns, or even specialized rifles.
