It sounds to me that a very good cleaning is in order.I would start with the gas system,to include the gas piston.the carbon biuld up is probably the culprit and your shotgun has never been taken apart and cleaned properly.
The steel part on the top of the gun where the gun can eject the bullet/reload.
It might need cleaning. It might need new springs/parts. You may need to switch brands of ammunition. You need to take it to a gunsmith for evaluation.

Give it a thorough cleaning.

Automatic weapons typically use recoil or a gas blowback system to eject the spent cartridge casing and reload the next cartridge from the magazine. Blowback systems use the gas from the powder ignition of the cartridge to eject the casing and reload the next shell. A portion of the ignited gas is redirected to force the action back far enough to reload. Most automatic weapons use this design. Recoil systems are just what it implies - the recoil from the ignited cartridge forces the bolt back and reloads the next.
You have a problem that needs the attention of a gunsmith. Browning's web site can point you in the right direction.
From Browning's website - "allowing the shooter to retain shells in the magazine and eject a shell from the chamber without feeding from the magazine."
Certainly. Or, you can use a competent independent gunsmith - sounds like an easy fix. www.countrygunsmith.net
Yes, it has a straight down bottom eject.
The factory installed CD changer is in the console. Open the sliding door. There is an eject button. Put 'em in, reload cartridge.
Keep gun pointed at target for 30 seconds. If gun does not fire, eject cartridge, reload with fresh cartridge, attempt to fire.
