A.1.1) Fixture No fixture required

A: 1.2) Tools No tools required

A.1.3) Procedure

White keeping your finger outside the trigger guard and pointing the muzzle in a safe direction, depress the magazine catch (36) and remove the magazine (33). With your finger still outside the trigger guard and the muzzle still pointing in a safe direction, grasp the slide from the rear and briskly pull the slide fully rearward to eject the round from tbe chamber and lock back the slide with the slide stop lever by using upward pressure with your right thumb. Do not obstruct the ejection port because doing so can interfere with ejection of a cartridge and thereby creates the risk of exploding an unchambered cartridge and possible injury. Visually inspect the chamber to be sure it is empty. Unload the magazine by holding it with the bullet end of the cartridge pointing away from you and pressing each cartridge forward and out of the magazine.

Decock the gun by pressing the decocker (4.2). Pufl back the slide (3) for approximately Irnm and push the takedown catch (23) downward at the same time and remove the slide from the frame (29) by pulling it to the front.
