Smith & Wesson J Frame Model 640 Trigger .236" Width Used .38 Special - JS192F

Smith & Wesson J Frame Model 640 Trigger — .236" Width, Used

Part Lot # JS192F | Used | J Frame | .38 Special | .236" Trigger Width | DAO

Used OEM trigger for the Smith & Wesson Model 640 J Frame Centennial revolver chambered in .38 Special. The Model 640 is a fully concealed-hammer double-action-only (DAO) revolver designed for concealed carry — the internal hammer eliminates the possibility of snagging on clothing. This trigger measures .236" in width, which is the narrower smooth-face style preferred by many for a lighter, cleaner trigger pull feel.
