Get a pump, cheaper, more capacity, and at a realistic price range, more reliable.
And yes, I do have a number of SXS shotguns.
Plus, you can reloaded it without breaking open the weapon.
How is a pump more reliable than a twice barrel? My Father had an old hammer double barrel gun. It had a habit of firing both barrels at the same time if both were cocked. That never happened to me but, it knocked one of my Uncles down and stuck stock first in a creek bank. :0)
