How the Glock internal safety works.

Glock pistols do not have an external safety that be can engaged and disengaged at will. Instead Glocks have various internal safety

mechanisms to ensure the pistol does not fire a round unless the trigger is pulled, ie. not when dropped, knocked etc.
Rob has written a interesting blog entry explaining how the internal Glock safeties works.

Understanding how your weapons safeties work is also of critical importance. Glock, even though it has no external safeties is no exception.

So that out of the way we can begin discussing how Glock is looking out for you. As you may know the firing pin is under 2/3rds pressure when the slide is charged. As soon as you place a round in the chamber there is pressure, and therby a possibility, however remote, that the round may go off.

    I heard once that the Model 1911 .45 had a "barrel safety," where, if the barrel (muzzle) was depressed by contact with the target, it wouldn't fire. Is that true? Are there any sidearms with this feature?

    Yes. The barrel in a 1911 is fixed but the slide that operates around it and that cocks the hammer isn't. If you push on the business end of the pistol and the slide moves backwards then it pushes the hammer back and if the trigger is pulled the hammer can't strike the firing pin.

    It's called the "John Wayne" safety by some.
