The Heritage Gun Books 5th Edition S&W Revolver Shop Manual is a 207‑page, 6" x 9" softbound expansion of Jerry Kuhnhausen’s definitive guide to Smith & Wesson revolvers. Because S&W lockwork is fundamentally consistent across models, the manual applies to J, K, L, and N‑frame revolvers, from pre‑WWII classics to modern numbered models. It addresses common issues such as cracked frames, timing problems, and excess endshake, while also covering custom work like installing a crane‑locking ball, plus detailed sections on polishing and rebluing. Full step‑by‑step disassembly instructions include guidance on diagnosing damaged parts, and the manual also discusses post‑1997 MIM components, making it a comprehensive reference for both repair and refinement.
