You can still find the left hand Rem LSS as stated by the others. It is no longer in production, but they are out there. Savage is hard to beat for accuracy in my book.
Another option is the Browning Stainless Stalker. It is offered in lots of calibers in left hand up to the 375 H&H. Accuracy is excellent, but the Browning synthetic stock shows wear easily.
I own 2 of the lefty LSS's and one lefty stainless stalker. One Savage Tactical that shoots better than I do, but it is definitely not a carry gun.
also. I have found several leftys there. Good luck!
