I'm looking at purchasing this O/U in a 20GA with a 28" barrel. My problem is I haven't been able to specifically tell if this gun is available as a stock option in a LH or ambidextrous model. I have seen the exact gun in a 30" but not a 28". Also, would it be completely necessary that I have a LH model? I've never owned a LH shotgun and I haven't found it to be much of an issue, but this would be my first O/U. Any information or opinions would be greatly appreciated.
