Smith & Wesson 2nd Generation Lever Spring — Factory New OEM Part 104230000
Smith & Wesson 2nd Generation Lever Spring — Factory New OEM Part 104230000
Genuine factory new OEM lever spring for Smith & Wesson 2nd Generation semi-automatic pistols chambered in 9mm and .45 ACP. In S&W 2nd Generation DA/SA pistols, the lever spring provides tension to the trigger lever (also called the sear lever or trigger bar lever), which is part of the fire control linkage that connects trigger movement to sear release. A weak, broken, or missing lever spring causes inconsistent trigger reset, failure to reset, or failure to fire. This is a factory new OEM part manufactured to original S&W specifications and tolerances.
Condition: Factory New — genuine OEM part in original condition.
⚠️ 2nd Generation Only — This spring is specific to 2nd Generation S&W pistols. It is not compatible with 3rd Generation (4-digit model number) pistols. Verify your model number before ordering.
