I very rarely carry concealed. When I lived in Georgia it was often difficult to carry in the winter; it was not cold enough for a light jacket much of the time. When I did carry it was always a "pocket-type" gun. Here in Maine where the winters are snowy cold it's much easier to holster carry as long as the coat doesn't need to be removed. Otherwise it's again one of the pocket guns.
Back again in Georgia, I was easily able to carry a a full size Colt 1911 using a "slide" holster in the lower back covered by a slightly longer waisted short sleeve shirt. I could do this when working "plain clothes" as a LEO even in summer. Carrying something flat enabled this. Being small, anything else either "printed" or made it look like I was wearing a truss.
Should also mention that I owned, hunted and killed deer with an old CVA .50 cap gun indifferently assembled from a very inexpensive kit. A friend and his dad had at one point put it together and It was given to me upon his father's death. This is interesting since his dad had built some fine flintlock longrifles from a plank. Some slight tinkering with the nipple and the cheapo rifle was reliable, accurate and a sure-fire killer of whitetails.
