It is a lighter field gun; however, its fixed chokes in those constrictions will work well for trap.
Typically, trap guns are heavy - on the order of 8#+. Trap singles are usually shot with a trap-specific single barrel. That is not to say that you can't shoot trap singles with ANY gun capable of firing one round at a time. The question becomes - as you mentioned - whether the gun will hold up. Beretta makes good guns, it should be able to be repaired by any decent gunSMITH (i.e., not some Glock parts replacer)
Make sure it fits you well and you can move the gun easily as necessary, then go and enjoy!
