Smith & Wesson Side Plate Assembly .45 ACP & 10mm Auto 3rd Generation — Factory New Part 106990000

Smith & Wesson Side Plate Assembly — .45 ACP & 10mm Auto, 3rd Generation, Factory New OEM Part

Genuine factory new Smith & Wesson OEM side plate assembly for Third Generation full-size pistols chambered in .45 ACP and 10mm Auto. The side plate covers and retains the internal fire control components on the left side of the frame. A cracked, damaged, or missing side plate compromises the structural integrity of the action and can allow internal parts to shift or fall free. Replacing it with a genuine OEM part ensures a precise fit and proper retention of all internal components.
