There is a gentleman that is trying to trade a 696 for one of my other handguns. I do not know a lot about this model, so I would appreciate feedback from the experts on the board. I have read numerous stories regarding the cone, and would like to know if this is indeed a major issue. He says it has a 2.5" tube, but everything I read says they came with 3" pipes. If you could help me with the above questions, and value, etc I would be grateful. TIA
