RE: Over/Under thoughts.
Could you get a used one of a better brand at the same price?
Browning, beretta perhaps?
About the pivots. I dont know about strengh but to me it is a point to be able to divide the gun in two when I travel. It is easier to clean also.
I love myo/u and its what I use the most so Im all for you getting one. The feel for the gun is whats important I think. That is after all what oneis aiming with.
What about choke tubes?
