The weekend is over and 400 rounds down the pipe and the trigger worked great.
Now to your question, All the work was done on the trigger bar only. My way of doing it was to remove the plastic trigger from the metal bar (the hardest part for me) and then put the bar in the purge chamber and fire up the square wave Tig and add material to make the bar longer, Next surface grind to size, bore and radius on the mill, Shoot peen and trip down the street to heat treat the one thing I can't do. Last the standard polish and reinstall the trigger shoe. I wonder if hard chrome or some other DLC coating on it will improve it's performance.
This week I will make one more and try it in my gun (it has a Edge by Glocktriggers.com in it right now) and then switch them to see if any timing problems show up. It's very little travel to get the trigger safety off and then the drop and plunger safety and then let the striker go.
I will update when more testing is done.
