👉 A threshold weapon is a type of firearm designed to be loaded and fired through a specially constructed opening or threshold, typically at the entrance or gate of a building. These weapons are engineered to be concealed within a small, narrow opening, allowing them to be carried and stored discreetly without raising suspicion. When the user reaches the threshold, the weapon is ejected from its concealed position, often through a mechanism that aligns with the opening, and is then fired. This design makes them particularly useful for law enforcement and military applications where stealth and quick response are crucial.
