Defective hammer notch, or sear edge, or disconnector, or sear spring.
Do not use the gun until it has been properly repaired, as it could fire when the safety is taken off, or even go full-auto when you least expect it.
If it's been dropping to the Intercept notch like that very long, it has already ruined the sear edge if nothing else is wrong.

What RC said.
Trust me, you DO NOT want to be on the trigger of a 1911 when it goes rock and roll!!!

Check...
....Thumb safety cam clearance to sear. Too much gap. Regardless of condition of the sear and hammer(not saying they may not be bad) nothing should happen or move when the thumb safety is taken off.
If the hammer and sear are good enough to engage and hold when cocked, The thumb safety is your starting point
A simple test.....with the gun unloaded, cock the hammer, apply safety, apply and release pressure on the trigger with the grip safety depressed.
Now disengage the safety. If the hammer falls to halfcock, you have a Thumb safety issue. If it does not fall, check further... CW

Fix before you use it again!
Get her fixed straight away.
The guys have it right.
If she goes full auto
The third shot goes up your nose!
1911s can go full auto with a worn sear or sear notch or bungled trigger job, and letting go of the trigger wouldn't help, even if you could do it (you can't actually let go as the reflex is to grip tighter)

That hasn't been my experience...and I've seen a bunch of'em go burp. In fact, they can be controlled fairly well with one hand. With a firm two hand grip, and a full magazine letting go...and by holding on the lower left corner of a 12"wide X 16" high steel target...you can keep 3 or 4 shots on the target as the gun torques up and right at about 45 degrees. It's over so fast that the gun just doesn't have time to move very far.
Now...on to the glitch.
It's most likely the safety to sear interface...but the only way to see it is to cock the hammer...engage the safety...and pull the trigger with the safety engaged...then disengage the safety. What happens is that the safety allows enough sear movement to stage the hammer hooks right on the tip of the sear. If it allowed just a tiny bit more movement, the hammer would fall and wipe the safety off on its way down, and...because the trigger is being pulled...the gun would fire. The safety doesn't block the hammer. It only impedes it...a little. The degree that it does that depends completely on how easily the safety gets past the plunger.
I won't say that it's impossible that merely disengaging the safety would let the hammer drop unless the trigger is first pulled..but it would one of those things that I couldn't see happening. The condition could exist for years without causing a problem until you pull the trigger with the safety engaged.
In any event, it needs to be fixed. Fairly simple matter of fitting a new safety, but could possibly require a new sear.
