Tecolote,
"Cocked & Unlocked"?
I have read all the PR from Glock. Other arms also have internal safties to prevent the arm from firing if dropped.
I still consider a loaded Glock to be "Cocked & Unlocked" because it cannot be locked from firing by pressure on the trigger.
Other arms have an additional safety lever, or button or grip or squeeze or long DA trigger.
