This listing is for the Smith & Wesson N Frame Model 629-5 & Up Strain Screw, Round Butt, Stainless Steel (Used OEM Part 629141E) only.

Used factory original Smith & Wesson stainless steel strain screw for N Frame Model 629-5 and later dash variants with a round butt configuration. The strain screw adjusts mainspring tension, directly affecting trigger pull weight — a worn, damaged, or missing strain screw causes inconsistent trigger pull or misfires. Machined to OEM specifications, removed from a functioning revolver and inspected prior to sale.
