I received a Pirahna LB today that has more rust damage than the seller led me to believe. The body is in fine shape, the rear asa has some surface rust, but the grip is in horrible shape. What it does have that convinced me to pay the top dollar for it was the battle pump on it. I have never used one before, and I still need to use it in a game, but shooting it in the yard it was VERY comfortable. I have heard other people say before that they do not like them. Is there something that I have not experienced yet that will possibly cause me to change my initial opinion of the pump?
