I got my SA-20 and need to swap the safety direction since I'm a lefty.
I looked around and didn't find any info on the process.
I called and talked to Mossberg and was told the safety is not reversible.
I pulled the trigger group apart to install the M-Carbo lighter trigger return spring and pull the safety to have a peek as well.
It appears that it would be quite easy to reverse the safety plunger with a modification to the trigger.
Maybe this will help somebody in the future?

Found the parts at Numrich under an Armsan A612. https://www.gunpartscorp.com/products/675380
Ordered a trigger to see if I can make this work.
Looks the same to me.

I was able to file the new trigger to have the relief on the left side. I dropped the trigger off at my gun smith to have him fill the right side by brazing.
Reassembled and shot last weekend without issue.
