My SBE II has done it a couple of times but each time it has I know that I smacked it down in the blind a little hard on the butt. Since that has happened I check it frequently and be careful. But, it's pretty hard for me to say that Benelli sucks because of that.
I can understand and sympathize with the handle hitting some brush and causing it to not fire and how frustrating that could be, especially on pheasant when you don't get that many opportunities like you do with waterfowl.
If you shoot it well modify it with the new spring or do what others have suggested. If you don't, sell it. In good condition it should fetch within 100-200 of what you paid for it.
Good luck
