I only have a few #1 jumps , and I have held coon in them ,though it wouldn't be my choice for a coon trap. Also, all the underspring traps that I've ever seen already have the chain attached opposite the spring eye. One thing about them is if they are fairly new and strong they hold quite well. Just accidentally snap one on your hand sometime while standing in water upto your waist ,and try to get it off of using one hand. :shock: I have also heard it said, the if jump traps where still made, it would be intresting how they would have scored on raccoon BMP's ,as the spring uses up some of the space under the jaws when they are fired. I would probably disagree with this as jumps usually have a slightly larger jaw spread than a comparable long spring trap and would negate this advantage.
