I have the AL391 - just the latest model of the 390. I like it alot. I use it mostly for shooting sporting clays. I've never had a problem with the shells jamming, there's little recoil, it's fairly light, and the 391 (I'm not sure about the 390) has an adjustable stock - making fitting the gun quite easy.
I have been hunting with a 390 for the last 3 years. I have been more than happy with the gun.
I only had a problem once with some Winchester 3" steel shells. It was a VERY cold duck day and I thik that my lubricant just became too cold and actually hindered the action.
I like the feel of my 390 better than the 391. I just like the thicker forearm I think. (Probably just what you are expecting to feel as I shoot a Beretta 20 as well with a very slim Schnabel forearm.)
I do think I would enoy being able to shoot 3-1/2" shells as well. I have watched my partner clean up some wounded birds with his Winchester X2 that were out of range for me. On the other hand, he shouldn't be cleaning up my birds!
