That heavy trigger pull on the gauntlet may be the problem. It could be causing you to pull shots to the right. Try the two finger approach where your thumb is on the back of the trigger guard and the tip of your forefinger is on the trigger in such a manner as to make sure you are pulling straight back. Try that and see if it helps to keep the groups more on target. I had the same problem as you with my gauntlet because I was used to guns with much lighter trigger pulls and found that I was pulling the gun a tiny bit because of the pressure I was having to put on the trigger. When I started using the thumb and forefinger method, shots started falling in a much tighter grouping at my POA. HTH
