👉 The fs weapon, also known as the FSM (Flip Side Mechanism) or FSW (Flip Side Weapon), is a versatile and compact handgun design that utilizes a flip-side mechanism to fire its rounds. This innovative design allows the weapon to switch between two distinct firing modes: a single-shot mode and a semi-automatic or fully automatic mode, all within the same compact frame. The flip-side mechanism enables the weapon to eject the spent casing and reload the chamber in a single action, making it highly efficient for rapid fire scenarios. The fs weapon's compact size and unique operation make it a popular choice among enthusiasts and tactical users seeking a balance between portability and firepower.
