It sounds like a good Google search. I just did it, but don't feel like retyping all the stuff I learned. Go for it. Mark

Very little:

Urika: Mainly Mobil chokes, bent carrier

Urika II: Can be either Mobil or Optima, flat carrier

AL391 Mainly Urika/Urika II and 3" chamber

A391: Mainly Extrema and 3 1/2" chamber

Then there is the stock differences between sporting and field versions. Mark

Ulrika 2 is phoney wood pattern on stock . Both about the same other then that

I own both. Slight difference in gas piston design. Pistons are interchangable. I have Optima Bore on both. Both are target guns. My wood is a nice grade of walnut. Don't know anything about no fake or phoney wood. Beretta doesn't make stocks with that contact paper process they were doing years ago. They also have a an Extra Grain process on some guns which walnut is enhanced. The stocks are not pine or plywood as some believe. Kreighof uses the same process on some of their guns also. That new single break open gun KX6 KS6 whatever? I never experienced any carrier issues I'd like to think that's because I know how to load the gun and I shoot good reloads.
