I was just watching a video by Jerry Miculek and he said that when he shoots a lightweight polymer pistol, like a Glock , he will put his forefinger in front of the trigger guard. The purpose is to give it more stability.

I have never changed my grip for a Glock but I can see where putting your forefinger in front of the trigger guard would control the muzzle a little better.

Do you do that as well?
