Smith & Wesson Pre-37 Airweight Chief's Special J Frame .38 Special .240" Grooved Trigger — Blued

Part # J150 | Used | Pre-Model Number Era

Factory Smith & Wesson used blued .240" grooved trigger for the J Frame Pre-37 Airweight Chief's Special revolver chambered in .38 Special. The Pre-37 is the pre-model-number designation for the J Frame Airweight Centennial produced before S&W adopted model numbers in 1957–58. As a Centennial-pattern revolver, this is a double-action-only (DAO) design — this trigger has no single-action notch. The .240" dimension refers to the trigger width/reach measurement. Gunsmith installation recommended.

How to find your model number: Swing out the cylinder and check behind the yoke on the frame. Model numbers began in 1957–58. If no model number is present, your revolver may be a pre-model-number variant — contact us with your serial number for assistance.
