That about sums it up.The Hidden third bites are generally to small and don't fit well on the sides, that they're help in the axial movement would be minimal.Side clips do work but are a major pain in the backside to fit properly.They are beaten over the side of the barrels rather than welded on.

I understand what your saying about the amount of use the double rifle get's compared to a shotgun but it only needs to blow up once to do the damage.Would you want to be shooting something that every time you pull the trigger,you dont know if its going to kill you rather than what your pointing it at.
