I have always read and heard that you should use the tip of your finger to pull a trigger. I have always trained to put the trigger just before the first knuckle. A friend of mine shoots with the trigger between the first and second knuckle, and he is a great shot. I was practicing skills today by dry firing (still trying to find what works best for me) and i tried putting the trigger between by first and second knuckle. I had NO wiggle during pull. On the double action pull of my 686 and the pull on my sigma i was smoother with the trigger placed between my knuckles. So what is the reason for the tip? Please tell me before i start practicing something i am going to regret later.
