Introduced in the early 1980s. 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 which 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 manually moved forward and back after each double action squeeze of the trigger. This particular pistol features a number of cutaway sections highlighted in red to showcase the inner workings. The firearm is hand built and features a serrated blade front sight, notch rear sight, smooth trigger and hardwood grips. Includes two non-sectionalized side plates, extra grip panels, a large number of assorted small parts, and papers.
