A few hours and a few shots is nowhere near a realistic training period, and definitely does not satisfy your promise " But I wanted to make a good honest effort, and see if I liked it better."

Considering you have always been a finger shooter, the " glove release" might not have been the best choice for your first release. Perhaps you should have gone with a model that has a wrist strap and a longer barrel.

Until you became familiar with using a release, the wrist strap would help in pulling your string without putting your fingers to near the trigger, and the longer barrel would help keep the trigger out in front until the pull of the string put a stronger load on the trigger.

Put a steak on your eye and get back out there!
