👉 The mainstream weapon, often synonymous with firearms in contemporary society, is the semi-automatic pistol. These compact and portable firearms are widely used by law enforcement, military personnel, and civilians alike due to their balance of ease of use, reliability, and effective range. Semi-automatic pistols operate by automatically firing a burst of rounds when the trigger is pulled, then requiring manual cycling of the trigger to load and fire a single round. This design makes them highly efficient for quick responses in various situations, from personal self-defense to professional law enforcement operations.
