Its a heavy door with boarding on the other side, I drilled right through it. Door is from late 1940's I would think. I just thought what the hell I've done it now so I might as well finish the job. My question is though if it was supposed to be a fire door why is there a huge 2 inch (2.5cm) gap at the bottom?

Fire doors are normally filled with gypsum, not asbestor. I have never heard of a door filled with asbestos. The gap at the bottom is standard for undercutting the door to allow for different floor finishes.

Asbestos fibers are only dangerous if they are less than a very specific size. The size being that generated by grinding and sanding operation and in Microns which are darn small. Furthermore, the exposure time to such micron particles is in the YEARS, not minutes or hours. The lungs are infected only by these small size micron particles, not some big drill shavings that you have generated.
A firedoor can indeed have a gap at bottom, that because it is to withstand a flame for a set number of minutes or hour and BLOCK OFF heat transfer thru the door so that the adjorning space on other side of fire will remain cool enough for Product and/ or people to survive, Usually that Temp # is 95 F. The gap at the bottom is part of the door test that the manufacture had in the actual test before the door was rated. You can look at an installation diagram of a firedoor installation and you will see that the larger the door, the bigger gap is allowed.

I wouldn't worry about the asbestos. The only hazard to you would be the inhalation of "friable" asbestos fibers, and in the case of one drilled hole, there will not be any significant impact.
As for the fire-door vs. gap question, it would seem that the fire rating is no longer valid! Considering the age of the whole thing, anyone's guess is as good as another!

i would think it had a threshold at one time and was removed sometime through the years. I doubt asbestos in itself would hurt you. rather the dust gets into your lungs and acululates after years of use.
