How do you disassemble a smith Wesson model 459 pistol?

Answer 1

Remove the magazine and clear the chamber. Make sure the gun is NOT loaded.

Set the safety in the up "fire" position.

Pull the slide back just enough so the slide catch notch in the bottom left side of the slide is even with the front of the slide catch.

If you pull the slide back far enough to engage the slide catch you have gone too far.

When the notch in the slide is over the pin of the slide catch push on the pin from the right side of the frame.

The button like end of the pin is just above the trigger on the right side of the frame.

Push in this "button" you may need something like a pen if you cant push it with you finger.

Fully remove the pin from the frame.

Pull the slide forward out of the frame.

Carefully remove the recoil spring and guide. Rotate the barrel bushing to the left and remove from the slide. Pull the barrel up and out of the slide. This is the standard field strip for this gun. Refer to a gun smith for further disassembling.
