A couple of years ago, I had misplaced my glove and couldn't find it in my pack when I got on stand. As luck would have it, a nice 10-point came by about mid-morning. I never thought about it, just shot him with bare fingers on the string.
Somewhat the same thing happened last fall. It was very cold, and I had my tab (changed from a glove to a tab) in my pocket. Just got on stand, and the buck was upon me. No time to fish the tab out of my pocket. Again shot bare fingers. Worked fine.
I'm considering not using a glove when I hunt. Can't shoot many arrows without a glove or tab without the fingers beginning to hurt, but one or a few arrows are no problem. Just one thing less to forget or go wrong.
