Don't want to let you down
Quick searching while waiting at some traffic lights.
Best I'm willing to do while driving
Pull the trigger allowing the hammer to free fall forward on the empty chamber. Do not "ease" the hammer down by holding or blocking it. Doing so can mar the sear tip which will result
in a substandard trigger pull.

All in all this thread is about gun shop etiquette, so just ask the guy, if he wants it done a certain way then do it that way.
The gunsmith told me about when I was handling his target 1911 with a 2# trigger. Perhaps the ones with a 5-6 pound pull may not be affected as much.
