Product Details
Genuine Smith & Wesson factory rebound slide assembly for the K Frame Model 19-4 revolver. This critical action component includes both the rebound slide and rebound spring. The rebound slide controls trigger reset and return, ensuring smooth double-action operation and proper trigger function. Essential for maintaining reliable trigger performance in your classic S&W revolver.
About the Model 19
The Smith & Wesson Model 19 Combat Magnum is one of the most iconic revolvers ever produced. Introduced in 1955 at the request of legendary lawman Bill Jordan, the Model 19 was designed as a lighter-weight .357 Magnum built on the medium K Frame instead of the larger N Frame. The Model 19-4 represents the fourth engineering change in the Model 19 series, produced from 1977-1982. These revolvers are highly regarded for their balance, accuracy, and smooth action.
Function & Compatibility
The rebound slide is a critical component in the trigger mechanism. When you pull the trigger, the rebound slide moves forward, allowing the trigger to travel. When you release the trigger, the rebound spring pushes the rebound slide backward, which resets the trigger to its forward position. This assembly is essential for both single-action and double-action operation.
This rebound slide assembly is specifically designed for Smith & Wesson K Frame Model 19-4 revolvers chambered in .357 Magnum (also fires .38 Special). The dash number (-4) indicates specific engineering changes, so verify your model variant for proper fitment.
Model 19 Engineering Changes
The Model 19-4 was produced from 1977-1982 and featured several improvements over earlier versions. The dash number system indicates factory engineering changes. While many internal parts interchange between dash variants, it's important to verify compatibility with your specific model. The rebound slide assembly is a wear item that may need replacement after extensive use.
How to Identify Your S&W Model
To determine your Smith & Wesson revolver model number, swing out the cylinder and check behind the yoke on the frame for the model number stamped into the metal. You should see "19-4" or similar. Model numbers began in 1957-58. If no model number is present, your revolver may be pre-1957. Contact us with your serial number for assistance in identifying the correct parts.

Trigger Performance Notes
The rebound slide assembly directly affects trigger feel and reset. A worn rebound slide can cause gritty trigger pull, inconsistent reset, or trigger binding. The rebound spring tension affects trigger return speed and feel. This assembly is essential for maintaining the smooth, crisp trigger action that made the Model 19 famous among competitive shooters and law enforcement.
