If you want an auto just for upland the Monte is hard to beat. Bothe the Monte andAL391 are very slim thru the forearm and balance with more weight towards the stock. Bothof these attributes are good in an upland gun. The Monte is lighter and a little longer in over all length. Both have automatic magazine cutoffs with cartridge release buttons. The AL391 also has the bolt lock lever on the left side of the receiver. Both models come with shims to adjust the stock. The Monte holds five shells totaland the AL391 four total and neither can take an extention. The Monte only comes in W/B and the AL391 in W/B, B/S, and camo finishes. The Monte is way easier to clean than theAL391.
The Monte is more of an upland specialists. Only the Franchi AL48 is as good or better for pure upland hunting.
