I use the shooting sticks for ground still hunting, a homeade rest that screws into the tree (for treestand hunting-kind of like the video camera support they are now selling), and a monopod for the stalking/moving hunt. The monopod has a homeade rest on top of it, so it will support the front forearm and the frame at the back. It is EXCELLENT for longgun and pistol hunting and probably would be my choice if I could pick one support item for my pistols. I made it from a camera monopod from Walmart, a dowel, female camera adapter (hardware store), and a block of wood. Total cost about $11.50.
Wish I could claim credit for the idea, but I think I found the plans on the HandgunHunting webpage. It is extremely portable and adjustable for the on the go pistolaro (sp?),
