Interesting, someone always seems eager to solve a problem which doesn't exist. I've always preferred double triggers because I like having two different chokes or even two entirely different loads available by just selecting which trigger to pull. I wonder how that non-selective single trigger would work if you only cock the left hammer. My guess would be that it would not work because the right hammer would still be at half cock safety position so the trigger would not pull.
In a true SXS this is the case where you can have instant options for choke or loading. But with these they are more of a target gun and will be loaded for cowboy action or personal defence. For target shot would be used and for personal defence buck or ball will be used.
From what I understand the trigger is either a one two and you may have to pull it twice to get just the left barrel to go. Or worse a rebounding trigger that need recoil to reset the trigger like on a Beretta or Browning or SKB single selective trigger in order to get the trigger to swap over to the second barrel.
Either way these are more toys than hunting guns with no chokes.
I can see putting low profile rifle sights on the Cavalry SXS and using it for deer with a buck and ball load in the right barrel and buck in the left.
