Might be a little more important to DISENGAGE the safety in a easy, timely manner.
Seriously though, Midway carries Fortmann drop-in lefty safeties(but won't ship to Canada), or a gunsmith can convert it but involves drilling new holes in the trigger group housing.
I think I saw one at Numrich too, but their 25$ per order fee makes my orders from them a little less often now.
