Yes, it's possible.
However, the act of removing or overriding an existent safety may expose you, and unnecessarily so, to liability.
I also think that the liability issue of altering firearms is a myth
On the other hand, for those among you thinking "this is a U.S. CCW myth", I would suggest you consult with (former RCMP Cst.) Michael Ferguson, who three times stood trial in Alberta for an Oct.3, 1999, shooting of one Darren John Farley in the Pincher Creek (Detachment) cells.
I'll quote from the Canadian Press report:
"The Crown also pointed out that three safety features on the officer's 9-mm hand gun were removed."
He was eventually found guilty of manslaughter.
Just a myth? Yeah, sure.
Personnaly, in a quality gun I can't really feel a difference between a trigger with/whitout the disconnector...
I'm sure if you look hard enough, you'll find somebody who had issues with it. But the only thing I've seen go wrong on a 1911 is a broken sear.
I had a colt combat elite, and the trigger was absolute crap. My springfield was a much nicer gun......
