Smith & Wesson K Frame Model 10 Cylinder & Yoke Assembly .38 Special 6-Shot Blue | Used OEM Part 1070A
Smith & Wesson K Frame Model 10 Cylinder & Yoke Assembly (.38 Special, 6-Shot, Blue) — Used OEM Part #1070A
This listing is for one (1) used Smith & Wesson OEM cylinder and yoke assembly, Part #1070A, for the K Frame Model 10 in .38 Special. Blue steel finish, 6-shot cylinder. Good used condition.
This is the complete cylinder group assembly including the cylinder body, extractor star, ejector rod, and yoke (crane). The yoke is the swing-out arm that carries the cylinder assembly and locks into the frame when the cylinder is closed. Part #1070A is the variant fitted to 4" barrel and longer Model 10 revolvers — the yoke arm length is matched to these barrel configurations. It is NOT intended for 2" snub-nose variants, which use a different yoke specification. Genuine Smith & Wesson factory OEM assembly.
Condition Note: This is a used assembly in good condition. Normal wear consistent with use and age. Blue finish may show holster wear, handling marks, or cylinder drag line. Cylinder timing and lockup have been verified. Professional fitting and installation by a qualified gunsmith is recommended; cylinder timing should always be verified after installation.
Caliber Note: This cylinder is chambered for .38 Special only. It will NOT safely chamber or fire .357 Magnum cartridges (shorter cylinder length). Do not attempt to use .357 Magnum ammunition in a .38 Special cylinder.

Model Compatibility
| Model | Caliber | Barrel Length | Finish | Compatible |
|---|---|---|---|---|
| Model 10 (4" barrel) | .38 Special | 4" | Blue | ✓ Yes — confirmed fitment |
| Model 10 (6" barrel) | .38 Special | 6" | Blue | ✓ Yes — verify yoke length |
| Model 10 (2" snub-nose) | .38 Special | 2" | Blue | ✗ No — different yoke specification |
| Model 64 (stainless) | .38 Special | 4" | Stainless | ✗ Verify — cylinder may fit but finish will not match |

Note: Part #1070A is confirmed for Model 10 .38 Special revolvers with 4" and longer barrels, blue finish. The 2" snub-nose Model 10 uses a different yoke variant. .357 Magnum models are NOT compatible — the .38 Special cylinder is shorter and unsafe for .357 Magnum ammunition. As a used assembly, gunsmith verification of cylinder timing and lockup is required before returning to service.
