I have the same set up in a 16 ga. L.C. Smith hammer gun. I got this gun in a basket. Never noticed how the tirgger were and I still haven't figured out how the front trigger fires the left barrel. The sear isn't long enough to reach over and you can't swith the triggers around. As Bobby said it might have been for a left hand shooter, as the right barrel is tighter than the left.
One of these days I will have to take it apart and look at the trigger housing. As for now, I just shoot it and don't think much about it.
