I shoot a beretta o/u with LH wood and a Benelli LH M2
I sold all of my Beretta autos (3) to switch to a LH Benelli M2. If Beretta offered a LH gun I would have went that way. I made the switch to LH after years of fighting the dominate eye. My Sporting Clays scores improved.
My M2 had some jamming problems with low base at first. after 500 rounds it has been flawless.
If I was right handed my personal favorites were the older Beretta 390. Beretta Autos are awesome
I also had the 1st gen extrema and a 391Urika as well all great guns.
I tried to stay with Beretta, I even faked it for a while shimming the Stock Cast to LH and flipping the safeties on the 390s.
While duck hunting in poor light I got to see (closely) how much I was exposing my eyes to the flash/gases that come from the reciever shooting 3in. mags.
I bought a Benelli LH the week afterwards. Some say if you get a Gas Gun wet enough it will fail.... I have never had that happen.
You really cannot go wrong wth either Beretta or Benelli. Both guns can be shim adjusted to fit and that is really a big deal the more you shoot.
Good luck with your search
