I don.t see any mechanical problems with that. Except you have to remove the forearm every time you change. That by itself I don't like.
Besides I am happy with the ejector and my manual notch extractor if a case gets stuck. I would not want an extractor. All my double shotguns have automatic ejectors, don't know why I would want an extractor besides they are sign of a cheap gun. Ouch :roll:
In my experience only worn and stretched brass seams to stick in a polished chamber and of course too hot a load. So at the range and shooting gophers I don't worry about a stuck case.
When I go hunting I use new brass and that wont stick. If I don't need a second shot my hand catches the empty. Sofar I have not needed a second shot. You all know the Handi is a one shot shooter ,ha
