The disconnector is a critical safety component that prevents the pistol from firing out of battery and ensures the trigger resets properly between shots in the DA/SA (double-action/single-action) system.
About the Model 39:
The Smith & Wesson Model 39 was introduced in 1954 and became one of the most iconic American 9mm pistols. It features a DA/SA trigger system, alloy frame for reduced weight, and single-stack 8-round magazine. The Model 39-2 represents a specific production variant with refinements to the original design. Parts for these classic first-generation pistols are increasingly difficult to find.

The blue finish shows typical handling marks. Used parts offer an economical solution for repairs and restorations while maintaining OEM quality and fit.
Installation:
Professional gunsmith installation is strongly recommended for proper fitting and function. The disconnector is a critical safety component in the fire control system that requires proper installation to ensure safe and reliable operation. Improper installation can affect safety and reliability. Knowledge of Smith & Wesson semi-automatic pistol mechanisms is required.
