Close.
In fact, the "conditions" were articulated by Jeff Cooper specifically with respect to the 1911. To be accurate, they don't apply to the M9 at all.
Condition 1 is "cocked and locked."
There is a condition system for every small arm and they teach you what it means for that weapon. I forget some of the belt fed stuff, wasn't qualifies on it. Pretty standard for any mag fed semi-autos and the pump shotguns we were around. They crib Cooper pretty hard for the conditions and four rules. Which is fine by me. The condition codes are used in communications for watch procedures and where I was in range commands, so they do apply. Had them used on the line at fleet matches too.
From memory.
Condition 1: Magazine inserted, round in chamber, slide forward, safety on.
Condition 2: Does not apply to this weapon.
Condition 3: Magazine inserted, no round in chamber, slide forward, safety on.
Condition 4: No magazine inserted, no round in chamber, slide forward, safety on.
I have qual'd on the M9, M11, Mossberg 12ga, and M16A3. Never carried an M11. M9 was always C1, shotgun always C3. 16 was C1. The only oddity in my extensive(LOLWUT) naval small arms experience is that I actually earned my expert medals(unlike every clerk who wears them) and I did it with an M-1A and a 1911, certified by percentage of score in competition rather than a 25yd goatrope which seems to be the best you can normally hope for in a rifle qual.
