I just bought a Beretta 682 Gold E Trap combo,
Factory left handed. What a beauty to shoot. Right out of the box it handles well. It improved my score dramatically right away without making any adjustments.
The gun fits well and some adjustments are being made. I can't wait to get back out there and give it another try. Bravo Beretta

Are they offering sporting versions in LH now?

I had to restock my 682 to get a left hand a few years ago

The answer would be a yes. Here's a link to the place I bought mine. They show 3 or 4 different versions of the sporting model left handed available now.
