Smith & Wesson J Frame Model 43 Airweight Trigger

Part# 183-43-R | .265" Trigger | .22 LR (Rimfire) | Blue Steel | Used Part

The trigger is the primary fire control interface of the revolver — it initiates both the cylinder rotation and hammer fall in double-action mode, and releases the hammer in single-action mode. This is a .265" wide trigger (standard width) in blued steel, specific to the Model 43 Airweight. A worn, cracked, or damaged trigger can cause inconsistent pull weight, failure to reset, or unsafe conditions. This is a genuine S&W factory used trigger pulled from a Model 43 Airweight and ready to restore proper fire control function.
