I use this for hunting in the deep woods in WI. I added a red dot sight. Its an 8 3/8" barrel. I haven't shot a deer with it yet, but I think if I do my part, its very accurate for the hunt, and beats charging through the thick with my rifle.
I love the gun and don't think barrel length matters unless you are shooting groups. The longer barrel really looks great with a sight on it, wish I had a current pic.
