LM-4 was designed as ultimate police backup/defense weapon. Manually operated 5-shot repeater only 5.2" long, 3.7" high and 1" wide. Chambered for .45 ACP. Undoubtedly smallest 5-shot .45 ever produced. LM-4 made of a special tool steel. Blued or at extra cost hard chrome-plated. Stainless steel version also available. LM-4 is not a semi-automatic, although it physically resembles one. Slide is flicked forward and back after each double-action squeeze of the trigger. This weapon is virtually hand-built. Features high visibility sights and smooth trigger. NOTE: Add $200 for hard chrome; 35 percent for stainless steel.
