I carried a 4 shot pump similar to this one -- but with just a shortened wooden forearm when I traveled the Florida swamps all day and night on foot as part of my business of finding cheap land.
It was not that bad to shoot and with practice I was able to aim it pretty well two handed.
Most of all, in country where gators, snakes, wild hogs, wild Brahma bulls, wild Long Horns, Cougars, Bears, armed bad guys, etc. roam... and I was often 10 or more miles from any road... it was a nice feeling to have it sitting over my right shoulder in a soft plastic tube which was attached to my pack frame. It made for a pretty fast draw and more peace of mind than other stuff I carried.
