Just found this forum after doing a search for left hand shotguns. I have a safe full of right hand semi's and a couple of break actions, but have always wanted a lefty in something other than 12 ga. After a total of 6 shoulder surgeries, 4 on my left and 2 on my right, I started looking in the 20 and 28 ga range. Beretta has the a400 Action in lefty but only in 12 ga. Benelli I think has the Montefeltro in 20 ga but only in black plastic and I think the M2 in lefty chambered maybe for 12 and 20, again only in plastic stock. The price tag of the O/U and SxS models keep me from looking that way.
If someone has found something in 20 or 28 dressed in something other than plastic, I would really like to know.
