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.
