Smith & Wesson Model 39 / 39-2 Sear Housing Insert — Used OEM Part #39-N

This listing is for one (1) used Smith & Wesson OEM sear housing insert, Part #39-N, removed from a factory Model 39-2 9mm pistol.

The sear housing insert (also called the sear housing block or frame insert) is the precision-machined sub-frame component that houses the sear, disconnector, and trigger mechanism within the pistol frame. It is one of the most critical fire control components in the Model 39 platform — essential for proper sear geometry, trigger timing, and safe operation. This is a genuine Smith & Wesson factory part in used condition, inspected for functionality — ideal for repair or replacement of a worn, cracked, or missing original.
