Smith & Wesson Model 39 Series Magazine Release Nut Blue Factory New OEM - 244650000

Smith & Wesson Model 39 Series Magazine Release Nut — Blue, Factory New OEM

Part #244650000 | Factory New | Model 39 / 439 / 539 | 9mm | Blue Finish | OEM

Genuine factory new Smith & Wesson magazine release nut for the Model 39 series 1st and 2nd Generation 9mm semi-automatic pistols. The magazine release nut threads onto the magazine catch post from inside the frame, securing the magazine catch button and spring assembly. A loose or missing nut causes the magazine catch to become wobbly, reducing retention force and potentially allowing magazines to drop unintentionally under recoil or handling.
