Smith & Wesson Manual Safety Plunger Spring Old-Style Factory New OEM Model 39 59 - 060790000

Smith & Wesson Manual Safety Plunger Spring — Old-Style, Factory New OEM

Part #060790000 | Factory New | Old-Style | Model 39 / 59 Series | 9mm | OEM

Genuine factory new Smith & Wesson manual safety plunger spring, old-style design for 1st and 2nd Generation S&W semi-automatic pistols. The manual safety plunger spring tensions the safety plunger detent, providing positive tactile click when engaging or disengaging the manual safety. A weak or broken spring causes the safety to feel loose, fail to click positively into position, or drift between safe and fire settings — a critical safety issue that warrants immediate replacement.

The old-style designation distinguishes this spring from the later 3rd Generation manual safety spring design. This part is specific to the early S&W double-action semi-automatic platform: the Model 39 (introduced 1955 — S&W's first successful DA/SA semi-auto, single-stack 9mm) and the Model 59 (introduced 1971 — the double-stack 9mm variant).
