I have had the same Zabala 410 since I was Twelve. It was my first shotgun that I bought with paper route money for $84.00 in 1972 at Kmart.When opened it has never fully dropped down to where the shell will clear the breech freely . It has always had a rebound making it a PITA to load and unload.I always pointed down and wrapped my left leg over the barrels. It would be nice to know of a fix.
