This listing is for the Smith & Wesson SD40 VE Housing Block & Pin, .40 S&W (Used OEM Part SD40VE4) only.
Used factory original Smith & Wesson housing block and retaining pin for the SD40 VE semi-automatic pistol chambered in .40 S&W. The housing block (also called the fire control housing or trigger housing) is the frame-mounted chassis that contains and retains the trigger, sear, and related fire control internals. The retaining pin secures the housing block in place within the frame. A cracked, damaged, or missing housing block or pin causes fire control components to shift or fail to function — a safety-critical replacement. Removed from a factory firearm and inspected prior to sale.

Installation Note
