Now I know this seems a little odd, but give this a try. Instead of using your normal trigger finger to hit the release, "which is the problem causer", slide your release over and activate it with your middle finger. It will not effect your shot as far as accuracy. You will punch the trigger far less if at all. Sometimes it is an instant cure. Seems odd, I know, but trust me and give it a try.
Let me know if it helps,
