I would go with the 5" gun and leave it with open sights if you're content to hold off if shots extend beyond 50-60 yards. I've kind of gotten into hunting with my 4 3/4" inch gun in the past couple of years and it's definitely more challenging but it has certain advantages too. I like it because it's easy to carry and it's just more handy than a long barreled gun. Nothing you ever shoot will know the difference in velocity between the 4 or 6 inch versions. I'm pretty sure if I had chosen to shoot at that big hog last weekend with my 4 3/4 gun I would have connected but I really had the wrong bullets in it for that large a hog.
