Me, I don't have anything in ANY of my pockets when I'm shooting ('cept the money clip). Don't wear no watch. Don't wear any rings. Don't wear jewelry of any kind. I like to be lightweight, free & easy when I'm playing.
FTR, I usually carry things (cellphone, keys, wallet) around in my hands as opposed to putting them in my pockets, with the exception of my money clip, which ALWAYS goes in my front pocket. If I need my hands free for something, then I will put these items in my pockets until my hands are free again. I just don't like things in my pockets.
