I have posted the following info on another website long time ago.
I do not remember if I have posted it on CGN.
I think this post should come with all the necessary disclaimers.

One thing that bothers people is the mag disconnect safety on the GSG1911.
If I had a GSG1911 and I want to disable the mag disconnect safety,
then I would choose this very easy way.
There is a part that looks like this:
It is located on the spring housing:
Under the tension of that little spring,
that part works as an "arrestor"
by restricting the movement of the beaver tail.
Therefore, the gun cannot fire because the beaver tail cannot be pressed.
When the mag is inserted, then
the tab on the left side of the mag pushes up the "arrestor",
which, in turn, will un-lock the beaver tail safety (that is,
the beaver tail can be pressed now in the "fire" position).
By removing the "arrestor" and its little spring, the
the gun will fire without a magazine.
However, I would not expect any other big things to happen.
It would not ease the functioning of the whole gun
(like removing the magazine safety in the Ruger Mk3)
It would not lighten the trigger pull
(how some people try to make you believe).
It would only make the gun to fire without a mag inserted. That's all.
However, I will not do it, because I don't have a GSG1911.
Cheers
