Smith & Wesson SD40 VE Housing Block & Pin .40 S&W - Part# SD40VE4

Smith & Wesson SD40 VE Housing Block & Pin

Part# SD40VE4 | .40 S&W | Used Part

The housing block (also called the fire control housing or trigger housing) is the frame-mounted chassis that contains and retains the fire control components of the SD40 VE — including the trigger, sear, and related internals. The retaining pin secures the housing block in place within the frame. A cracked, damaged, or missing housing block or pin can cause fire control components to shift or fail to function, making this a critical structural part. This is a genuine S&W factory used housing block and pin pulled from an SD40 VE.
