If you are really hung up in ambi check out beretta most all of their handguns have an ambi safety and mag release. Stoeger cougar as well. Personally I'm left handed as well and My range guns are traditional right hand guns but my carry guns are a beretta 84 (cheetah) and soon to be a Nano. The nano's Mag release is switchable for a lefty and its got no external slide catch. So if you're looking for a good concealed carry handgun the nano may be worth checking out too.
