Are you planning to strictly use this shotgun for slug hunting, or did you also want to have a smoothbore barrel for wingshooting? Although a little more expensive, the Browning BPS may be a better choice for you. (

It's not a true southpaw action, but the top-tang safety and bottom-ejection works great no matter how you shoot. The Deer Hunter model is already equipped for slug hunting, but is one of the more pricey models. Since the action is ambidextrous however, you could purchase a separate rifled barrel for a cheaper model, and be able to use it for pretty much anything you want to shoot at. Good luck, you can't go wrong with the Browning or Remington.
