[Shooter 2.5]

* All firearms are loaded. - There are no exceptions. Don't pretend that this is true. Know that it is and handle all firearms accordingly. Do not believe it when someone says: "It isn't loaded."
* Never let the muzzle of a firearm point at anything you are not willing to destroy. - If you would not want to see a bullet hole in it do not allow a firearm's muzzle to point at it.
* Keep your finger off the trigger until your sights are on the target. - Danger abounds if you keep your finger on the trigger when you are not about to shoot. Speed is not gained by prematurely placing your finger on the trigger as bringing a firearm to bear on a target takes more time than it takes to move your finger to the trigger.
* Be sure of your target and what is behind it. - Never shoot at sounds or a target you cannot positively identify. Know what is in line with the target and what is behind it (bullets are designed to go through things). Be aware of your surroundings whether on a range, in the woods, or in a potentially lethal conflict.

If that were true it would be rather difficult to field-strip a Glock.

I will accept that firearms should be presumed capable of reloading themselves any time they are set down, and should be kept pointed in a safe direction even when you can see into the chamber, but if a Glock can't be unloaded with enough confidence to allow pulling the trigger, how can it be field-stripped?
