I just bought a Thompson Contender G2 with a 14" barrel in .44 mag. I bought it to use for deer and I am trying to figure out the best type of holster for carrying it all day in the field. In Illinois it is cold during gun season so you can count on having to wear a heavy jacket/bib. There is no concealed carry allowed here so it has to fit over the heavy coat. I generally hunt from a tree stand and I want to be able to reach for my gun while sitting. Also I wear a Hunter Safety System vest which complicates things. Anybody have any suggestions, ideally based on personal experience, about the best way to carry a very large pistol in the field in cold weather? Thanks!
