Somebody messed with your Smith--the front trigger blade on double triggered shotgun, whether sidelock or boxlock, should always fire the right barrel, and the rear trigger blade the left barrel.

As I have a deep fondness for LC Smiths, especially the pre- 1913 graded Smiths, I'd consider keeping, send it to Master Smith Gunsmith Buck Hamlin in Peavely MO-- have him open the chokes a bit, and get the trigger set-up un-fubared" and shoot it until it becomes as much as part of you as possible.

I'd also have Buck glas-bed the stock in the locks and tangs areas, and as I do with my 5 Smiths- shoot lighter loads, which kill just as well as the big boomers, and are easier on your: gun, shoulder and wallet. RWTF
