Hi Steve and welcome. The Citadel would work no issue for self/home-defense duty. I would steer you towards the Winchester due to superior parts availability for any potentially needed repairs and better customer service availability for any warranty work. Cheers, stay safe and enjoy!

The Citadel Mariner is an excellent choice. Reliable and since it’s a pump action, it’s easy to use. 👍🏻💯❗️

yes it is a very good home defense shotgun

Hi Steve, both the Citadel Mariner and Winchester SXP Marine Defender are considered good options for home defense due to their reliability and ease of use. They are designed for defensive purposes, making them suitable choices for protecting your home.
Personally, I would go with the Winchester XPS (Super X Pump). Winchester bills the SXP as “the world’s fastest pump-action shotgun,” and not without reason. The SXP’s bolt features four locking lugs that disengage and begin traveling rearward under recoil, which boosts operating speed and reduces the force required to cycle the action. I myself have had a Winchester for many years and it has served me very well.
Stay safe & have a great day!

Both the Citadel Mariner 12 Gauge Pump and the Winchester SXP Marine Defender are considered good, affordable choices for home defense, particularly for those needing a corrosion-resistant "weather-proof" gun. They are both pump-action, 12-gauge shotguns with 18-inch+ barrels and marine-style finishes.
Here is a breakdown of how they compare for home defense based on user feedback and specifications:
1. Citadel Mariner 12 Gauge Pump
Pros: Highly affordable with great value, often including extras like a picatinny rail, shell holder, and choke tubes. It has a robust reputation and is generally praised for its reliability and corrosion resistance. It is noted as a "light and handy" option.
Cons: Some users have reported that the pump slide lock can be awkward to reach, requiring a change in grip for follow-up shots. The finish is sometimes described as a coating rather than true nickel plating.
Verdict: An excellent budget-friendly, "no-frills" home defense shotgun.
2. Winchester SXP Marine Defender
Pros: Renowned for having an "inertia-assisted" action, which many users describe as exceptionally fast and smooth—often called the fastest pump-action in the world. It features a durable, matte chrome finish. It is considered very reliable and well-built.
Cons: The forend (pump grip) can be rough on the hands, and some users find it uncomfortable. The magazine capacity is 5+1.
Verdict: A step up in quality and speed from the Citadel, making it a stronger, though slightly more.
