And, there is:
Condition 4 - The chamber is empty, the hammer is uncocked and there is no magazine inserted in the mag well
And if that is not enough, some gun writers have come up with:
Condition 5 to describe: Chamber is loaded, hammer down, safety on, in
SA mode to describe the "
Fast-Action" of the
Fabrique Nationale patent which is widely used now-a-days on the
Daewoo...
P.S. A little known fact that when
FN entered in the competition for the new U.S. pistol in the early 80's, one of their two models had the "tri-action" trigger...Some of the leading gun authorities at that time thought that would give them an edge on being selected...Oh well, it didn't happen..
