The Taurus 1911 appears to closely resemble a Series 80 Colt's design.
If a round were dropped in the chamber and the slide dropped, this could cause extractor damage, but not an ACCIDENTAL DISCHARGE. An AD is the gun discharging WITHOUT the finger being on the trigger.
Likely a NEGLIGENT DISCHARGE, caused by having the finger on the trigger at an inappropriate time, is what the OP experienced..
The description earlier by a poster of having the finger on the trigger at an inappropriate time is very likely what happened. The 1911 has been around so long that the bugs were worked out a long time ago.
As far the inevitability of everyone having a ND, not so. After 50+ years in the gun culture, including high volume competition shooting, hunting, and extensive training, often in a Law Enforcement environment, I have yet to dump a round by pulling the trigger in a negligent manner.
I HAVE had AD's caused by broken parts and customer "fixes" when I gunsmithed. However, arms were pointed in a safe direction in a firing range.
Remember, the Primary Safety of ANY firearm is MUZZLE DIRECTION.
Another is ON TARGET, ON TRIGGER. OFF TARGET, OFF TRIGGER. These two rules will keep you safe anywhere you go.
The obvious rule of not having the arm loaded unless it is in use rounds out the envelope of safe gun handling.
I would get the firearm checked out by a good smith. After, get remedial training on the unique features of the 1911 platform.
A certificate to the judge that steps were taken to prevent a future issue will go a long way, if there is not a mechanical issue with your 1911.
