Bill, not specifically Sir. A left hand Custom Shop version is currently out of stock : budsgunshop.com/product_info.php/products_id/139630/ruger+31110+10+22+competition+22+lr+10%2b1+cap+1612%22

Bill, Ruger does make a LH version in the take-down model. There is a 10/22 LH competition model, about $300 more and out of stock. ruger.com/products/1022Competition/specSheets/31110.html

Here's something that may help. Not sure if this is one of the lefthanded models though.
