I have the same gun and am left handed too. It seems the best you can do for safeties is Tanfo part number 102117. The right side safety won’t be as big as the left side that’s on the gun now.
As far as flipping the safety, you have to almost take the entire lower end apart. The trigger has to come out then you can pull the magazine catch plunger out. I installed a CGW Canik trigger pin when I put mine back together. The slave pin that comes with the CGW pin makes reassembly a lot easier (the hard part is getting the trigger and trigger return spring back in).
