Installation involves internal action work and may require fitting to achieve optimal performance. Improper installation can affect firearm safety and function.
How to Identify Your Smith & Wesson Model
To confirm compatibility:
- Swing out the cylinder of your revolver
- Look behind the yoke on the frame for the model number
- Model numbers began in 1957-58
- If no model number is present, your revolver may pre-date 1957-58
If you have a pre-1957 revolver without a model number, contact us with your serial number and we can help identify the correct parts for your firearm.
About the K Frame Platform
The Smith & Wesson K Frame is a medium-sized revolver frame that has been in continuous production since the early 1900s. The term "hand ejector" denotes revolvers where the cylinder swings out to the left side of the frame, and empties are ejected by pushing the ejector rod. This time-tested design has proven reliable for over a century.
The Model 10, chambered in .38 Special, became the standard-issue sidearm for countless law enforcement agencies and remains one of the most widely produced revolvers in history.
⚠ Important: This is a used factory part in good working condition. All parts are inspected for quality and function. Some parts may require fitting by a qualified gunsmith for optimal performance.
