My first goal would be to find out if they actually know what a 1 pound trigger feels like. Many years ago I put a timney 2oz in an xp in 7IHMSA. I thought I knew what I was doing right up till the time I started trying to use it. It takes a lot of shooting to learn how to squeeze that trigger and not just trip it by touching it.
Being able to use a really light trigger is a two edged sword. I still fight most factory triggers and accuracy suffers accordingly.
