Model Compatibility
| Model | Revision / Frame | Compatibility | Verification Required |
|---|---|---|---|
| Smith & Wesson Model 18 | 18-4 / K Frame | Confirmed donor configuration | Match the slide profile, spring arrangement and lockwork geometry |
| Other K Frame revolvers | Rimfire or centerfire | Potentially compatible when dimensions and production-era geometry match | Model number alone does not guarantee fit; compare directly with the original assembly |
Compatibility note: Unlike a hammer, a rebound slide is not inherently rimfire- or centerfire-specific. However, Smith & Wesson made lockwork and dimensional changes across production periods. Fitment beyond the Model 18-4 configuration is not guaranteed by this listing.
Installation
Rebound slide replacement requires revolver disassembly, correct spring installation and trigger-return testing. Installation and final safety inspection by a qualified gunsmith are recommended. Used parts may show normal finish wear and handling marks; the photographed item represents the part and condition offered.
