Did you browse through the Opininion Forum ? You could also use the search feature for these two shotguns. I know we've had several discussions on the AL-391.
Hope it helps.
If you are going to need an adjustable stock some 'smiths won't put the hardware into a 391 because the placement of the stock bolt does not leave much room for the hardware. I have one in my 391 and have had no problems with my adjustable stock.
I love my 391, it is easy to clean easay to shoot and I would recommend it.
