Designed to be offered for use by clandestine services or as the ultimate police backup weapon, the LM-4 is a manually operated 5-shot repeater that is 5 1/4 inches long and is the smallest 5-shot .45 caliber pistol ever produced. The LM-4 pistol is not a semi-automatic although it physically resembles one. The slide is flicked forward and back after each double action squeeze of the trigger. The firearm is hand built and features a serrated blade front sight, notch rear sight, smooth trigger and black checkered plastic panel grips. The slide is numbered to the gun. Complete with extra magazine.
