About the Model 19-3
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 19-3 represents the third engineering change in the Model 19 series, produced from 1967-1977. This dash variant is highly regarded among collectors and shooters for its balance, accuracy, and smooth action. The 6-inch barrel version is particularly popular for target shooting and hunting.
Model 19-3 Specifications
The Model 19-3 features several improvements over earlier versions, including refined internal parts and improved heat treatment. The 6-inch barrel provides an excellent sight radius for precision shooting while maintaining reasonable portability. The 6-shot cylinder chambered in .357 Magnum also fires .38 Special ammunition. This configuration was extremely popular with law enforcement and competitive shooters during the 1970s.
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 19-3 revolvers chambered in .357 Magnum with 6-shot cylinders and 6-inch barrels. The dash number (-3) indicates specific engineering changes, so verify your model variant for proper fitment. May also fit other K Frame models with similar specifications.
Model 19 Engineering Changes
The Model 19-3 was produced from 1967-1977 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, particularly in revolvers fired with heavy .357 Magnum loads.
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 "19-3" 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.
