Rob Pincus demonstrates how to properly unload and clear a firearm.
The procedure he follows is to release the magazine and lock the slide open while in the high compressed ready position, not looking at the gun. Then look at the gun to check for rounds, leaving it locked open. Confirm with someone else that the gun is empty. Reholster the gun with the slide locked open and put the gun in its case. Rob also discusses why he does not pull the trigger to confirm the gun is unloaded.
