Compatibility & Fitment Guide
Compatible With: Smith & Wesson K-Frame revolvers, specifically Model 17-8 and Model 617-2 chambered in .22 Long Rifle. The hand is a critical internal component of the double-action mechanism that rotates the cylinder during trigger operation.
Model 17-8: The Model 17 is S&W's classic K-Frame .22 LR revolver with blued finish, introduced in 1957. The dash-8 variant represents specific engineering changes in the production run.
Model 617-2: The Model 617 is the stainless steel version of the Model 17, introduced in 1990. The dash-2 variant indicates the second engineering revision of this model.
Identifying Your Model: To verify compatibility, swing out the cylinder and check behind the yoke on the frame for the model number stamped into the metal. The dash number (e.g., -8, -2) will be stamped next to the model number. If you're unsure about your specific dash variant, contact us with your serial number for verification.
What Is the Hand? The hand (also called the rebound slide hand or cylinder hand) is the internal component that engages the ratchet on the cylinder's extractor star, rotating the cylinder to align each chamber with the barrel during double-action trigger pull or manual cocking.
Professional Installation Required: This is a precision internal fire control component. Professional installation and fitting by a qualified, licensed gunsmith is strongly recommended to ensure proper timing, cylinder rotation, and safety.

Who This Part Is For
This genuine Smith & Wesson factory hand is ideal for:
- Professional Gunsmiths: Armorers repairing or restoring Model 17-8 and 617-2 revolvers for clients
- Revolver Enthusiasts: Owners maintaining their K-Frame .22 LR revolvers with factory-correct components
- Collectors & Restorers: Those seeking authentic OEM parts to preserve originality and collector value
- Competitive Shooters: Bullseye and precision shooters maintaining reliable timing and smooth double-action operation
- Plinkers & Trainers: Owners of high-volume .22 LR revolvers replacing worn components from extensive use
Common Problem This Part Solves
Symptoms of a Worn or Damaged Hand:
- Cylinder fails to rotate fully or skips chambers during double-action trigger pull
- Inconsistent cylinder timing or alignment with barrel
- Rough or gritty double-action trigger pull
- Cylinder lockup issues or failure to lock into battery
- Visible wear on the hand or cylinder ratchet
Why Hands Wear Out: The hand is a high-wear component that experiences friction and impact with every trigger pull. In .22 LR revolvers like the Model 17 and 617, which are often used for high-volume practice and plinking, the hand can wear over thousands of rounds. Replacing a worn hand restores proper timing and smooth operation.
The Solution: This genuine factory hand provides the exact dimensions, material hardness, and surface finish required for reliable long-term performance. Unlike aftermarket parts that may require extensive fitting, OEM components are manufactured to S&W's proven specifications.
About the Smith & Wesson Models 17 & 617
Model 17: Introduced in 1957, the Model 17 is Smith & Wesson's legendary K-Frame .22 LR revolver, known for its accuracy, smooth trigger, and versatility. It has been a favorite for target shooting, small game hunting, training, and recreational shooting for over six decades. The K-Frame size provides excellent balance and pointability.
Model 617: Introduced in 1990, the Model 617 is the stainless steel version of the Model 17, offering corrosion resistance and durability. Available in 4", 6", and 8.375" barrel lengths, and in 6-shot or 10-shot cylinder configurations, the 617 has become one of the most popular .22 LR revolvers for competitive shooting, training, and recreation.
Why .22 LR Revolvers Matter: The .22 LR chambering offers low recoil, affordable ammunition, and exceptional accuracy, making these revolvers ideal for developing shooting fundamentals, competitive bullseye shooting, and high-volume practice without the cost and recoil of centerfire cartridges.
Installation & Gunsmith Services
Skill Level Required: Professional gunsmith strongly recommended
Tools Required: Specialized gunsmithing tools, punches, screwdrivers, fitting stones, and timing gauges
Replacing the hand requires complete disassembly of the revolver's internal action, including removal of the sideplate and internal components. This is a precision operation that requires:
- Proper disassembly and reassembly procedures
- Verification of cylinder timing and lockup
- Checking hand-to-ratchet engagement
- Ensuring proper cylinder rotation in both single-action and double-action modes
- Verifying barrel-cylinder gap and alignment
- Testing trigger pull weight and smoothness
Why Professional Installation Matters: Improper installation or timing can result in cylinder misalignment, which can cause dangerous conditions including bullet shaving, gas cutting, or catastrophic failure. A qualified gunsmith will ensure the hand is properly fitted and timed for safe, reliable operation.
Important Safety Note: Never attempt to install internal fire control components without proper training, tools, and knowledge. Always have a qualified gunsmith verify proper function and safety before firing.
