Gentlemen,
As a smith, and I am, the liability issue alone would make any modification that removes the disconnector out of any firearm a practice unworthy of mention. I personally would NEVER want to talk to the widow or worse yet her lawyer about WHY I removed any factory part from ANY firearm to make it LESS SAFE. I don't care how 'good' you are with your firearms, less safe is less safe. The reason a disconnector was added many years ago had nothing to do with liability or lawyers, it was done to simply make all firearms less susceptible to accidental discharge. It can still happen with modern day firearms, but it's really difficult unless the firearm has been modified or the internal parts are extremely worn. I won't own one, sell one or work on one that someone wants me to modify. I tell them to take it to the back alley and throw it away, as they will be better off than doing that modification.
As to the 'top one tenth shooter'. I have a short illustration. In Colorado Springs, less than five years ago there was an 'Olympic class shooter'. Made the team and everything. One day, while showing off to some of his friends in his own home, he put his own 1911 to his head and pulled the trigger. They buried him two days later. This is a gruesome but true story. You gets what you pays for.... so to speak. Or maybe stupid is as stupid does.
