Recently purchased "retired" (and abused) 5906 pistol. Pretty banged up with some surface oxidation, etc. Fortunately it already had the stainless hammer and trigger. Rehab included a thorough cleaning, and bead blasting of the exterior. Also installed new OEM springs. Replaced the worn out grips with a new original set, and the rear sight with a new Novak low mount. Overall, turned out better than I expected. S&W advised the mfg date was 03-06-1992. Shoots very well.
