If a trap gun is what ya want and if ya want it to be a semiauto then the 11-87 is as good as it gets in my opinion. I will say however that there are negatives to a semiauto as a trap gun. True it reduces recoil some but it also tosses your hulls. Other shooters to your right they are being tossed on just before it's their turn to shoot might not like that and you lose them if on ranges that don't allow you to pick them up. Even if the range does allow you to pick them up you delay the squad doing so.
Personally I prefer a pump, single barrel or O/U for trap but then that's me.
