Recently I purchased a Scott little Goose and it is fantastic, It certainly has helped improve my accuracy. They are a little on the pricey side anywhere from $50 to $70 dollars but they are the best and will help. If you have larger hands try the Mongoose by Scott basically the same as the Little Goose but just bigger. You might want to try sortening up your release if you can so that when at full draw the trigger falls at the first crease in your finger when your finger is bent at the second knuckle.
