I notice it has 2 triggers. I wonder if they are synchronized, or if they work independently?

they would have to work independently. other wise you would be shooting two bullets with one trigger pull.

I will wait for the over and under version. Now that will be some engineering!

Reminds me of the North American P82 Twin Mustang

but probably less useful.

Heck, twins have been around for a long time
