In my experience, gloves are hard on both metal and wood finishes. I try not to use them, if I must, because of the cold, I've found that thin, soft, clean deerskin gloves are easy on the rifle or shotgun and enough to keep wind chill from making your hands useless. A couple of pairs rotated to keep them bone dry seems to work for all but the coldest days. The fleece or wool gloves are not wind proof enough to me and make gripping the gun tough if they don't have leather palms.

But I pick up duck decoys from ice chunk filled water without gloves so my toleance is pretty high.
