On an "adjustable" trigger, there is a little hole in the front face of the trigger, near the bottom, and what appears to be a hex screw, or torx screw beneath it.
What does it do?

Lone, 1) I believe you are describing the overtravel screw, 2) it induces mals by binding the weapon so that it cannot fire.

I will chime in with my two cents worth.
My Colt Government enhanced had the stock plastic trigger so I installed an aluminum trigger with the overtravel adjustment.
The set screw lets you determine the total trigger travel with an eye on limiting the travel to the minimum right after you have pulled the trigger back far enough to let the gun fire.
To adjust it you first set the screw so that the trigger will not fire the gun. Then you keep screwing the set screw out until there is just enough movement to fire the gun.
The malfunction comes from setting the release too close and finding that you are back in the condition where the gun won't fire.
The cure, for me anyway, was to use blue lok tite and cement the set screw in place once I had it where I wanted it.
The objective of the adjustable trigger is to allow you to establish the minimum "reset" required of the trigger in order to fire again.
If there are other reasons someone else knows of, please chime in as I am not an expert, just an amature smith. I have put over 5000 rounds through my 1911 since installing the trigger and have not adjusted it again.

In a dirty enviroment it sometimes keeps the trigger from moving enough

On a 1911, it can also cause damage to the sear if to tight. The trigger ends up holding the sear hooks against the hammer as it falls, grinding up the hooks.
Generally, this is an unnecessary and potentially dangerous addition to a defense gun. But it can really help the feel of a target/game gun. It's certainly a foolish addition to the HK USP "Tactical".
Some solder the screw in place. Mine is.

Another non 1911 expert here but - on the subject of overtravel limitation ........
With my first M27 Smith which I used for practical revo .... I modified it .. by drilling out and tapping the combat trigger .... used a small Allen head set screw - on the rear of which was a small pad of hard rubber fixed with cyano .... I know this ain't a 1911 but ... once I got the right setting it vastly improved my rapid D/A work ... and the rubber buffer allowed for some safety factor such that full release was well before end of modified travel ... and yet it avoided a lot of ''unnnecessary'' further travel.
I would think this could be applied to an auto in a similar manner

Lone, the overtravel screw is a loose screw. Place it neatly over the berm.:D

Good point from Handy.
I would never have this set up on a defense gun.
My 1911 is strictly range and target. It is reliable and never has had a problem, but still it is a tweaked target gun that was never meant to be carried as a defense weapon.
My stock HK is my personal defense .45.
