About the Victory Model
The Smith & Wesson Victory Model was produced during World War II for Allied military forces from 1942-1945. Based on the Military & Police (M&P) design that would later become the Model 10, the Victory Model was chambered in .38 Special and featured a parkerized finish for durability in combat conditions. Over 570,000 Victory Models were produced for the U.S. military, British Commonwealth forces, and other Allied nations. These revolvers are highly collectible today and represent an important piece of WWII history.
Bolt Assembly Function
The bolt (cylinder stop) is a spring-loaded component that rises through the bottom of the frame to engage notches in the cylinder, locking it in precise alignment with the barrel. Proper bolt function is absolutely critical for accuracy, safety, and reliable ignition. The bolt must engage at exactly the right moment during trigger pull and hammer fall to ensure the chamber is perfectly aligned with the barrel and firing pin.
Function & Compatibility
The bolt assembly works in conjunction with the hand to control cylinder rotation and timing. As you pull the trigger in double-action, the hand rotates the cylinder while the bolt drops down to allow rotation. At the precise moment of lockup, the bolt rises to engage the cylinder notch, locking everything in alignment. This timing must be perfect for safe and accurate operation.
This bolt assembly is specifically designed for Smith & Wesson K Frame M&P Victory Model WWII revolvers and Pre-Model 10 revolvers chambered in .38 Special. It may also fit other K Frame .38 models from the same era - contact us to verify compatibility for your specific revolver.
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. Model numbers began in 1957-58. If there's no model number, your revolver is a pre-1957 model such as the Victory Model or M&P. Contact us with your serial number for assistance in identifying the correct parts.
