Smith & Wesson Model 60-10 .357 MIM Bolt Assembly - J632
Smith & Wesson Model 60-10 MIM Bolt Assembly
Used Smith & Wesson MIM bolt assembly, also called a cylinder stop, identified from a J Frame Model 60-10 revolver chambered in .357 Magnum. This part rises into the cylinder stop notches during the firing cycle and is a timing-critical component of the revolver action.

Model Compatibility
| Application | Compatibility | Required Checks |
|---|---|---|
| Smith & Wesson Model 60-10 | Confirmed donor/application identification | Match MIM construction, bolt nose profile, pivot geometry, spring/plunger arrangement and surrounding lockwork |
| Other later Model 60 revisions | Possible only after parts-level verification | Compare directly with the original bolt; production period or model family alone does not establish fit |
| Other J Frame revolvers with MIM lockwork | Not guaranteed | Verify engineering revision and every mating dimension |
| Earlier forged-lockwork J Frame revolvers | Not assumed compatible | Do not substitute without exact geometry confirmation |
Compatibility note: This bolt assembly is primarily frame- and lockwork-revision-dependent rather than caliber-specific. The Model 60-10 donor identification does not establish universal post-1997 or J-frame fitment.
Installation and Safety
Installation may require fitting to the individual frame and cylinder. A qualified gunsmith must verify free movement, bolt rise and drop, cylinder timing, carry-up, notch engagement, lockup and chamber-to-bore alignment before firing. Used parts may show normal finish wear and handling marks; the photographed item represents the part and condition offered.
