Description
When the stakes are high and the space is tight—like clearing a hallway or securing a room—you need a tool that’s instinctive, powerful, and utterly reliable. For the left-handed shooter, that often means compromising with a right-handed world. Not anymore. The Mossberg 500 Tactical, 12 Ga, 18.5″, 6rd, Blued/Synthetic, LEFT HAND is the definitive answer: a purpose-built, left-ejecting pump-action shotgun designed for home defense and tactical use, offering the legendary Mossberg 500 reliability in a true southpaw configuration.
Here’s the thing—this isn’t a modified right-handed gun. The ejection port is on the left side, sending spent shells clear of your line of sight and dominant hand. The safety is ambidextrous, positioned on the tang for easy operation with your thumb. From the moment you shoulder it, the controls work with you, not against you. At a total length of just over 39 inches and a weight of around 7 pounds, it’s maneuverable in confined spaces without sacrificing the heft needed to manage 12-gauge recoil.
Built for the Defensive Scenario
The 18.5-inch cylinder-bore barrel is the legal minimum for a non-NFA firearm, providing a compact profile ideal for indoor use without the muzzle blast of a shorter barrel. The cylinder choke delivers consistent patterns with defensive buckshot at close quarters. The 6-round capacity (5+1) gives you multiple engagements before a reload is necessary. The synthetic stock and forend are durable, weather-resistant, and provide a solid grip in all conditions. The blued finish on the barrel and receiver offers classic corrosion resistance.
This platform is famously modular. The synthetic forend is compatible with a wide range of aftermarket options, including lights and vertical grips from brands like Streamlight and Magpul. The receiver is drilled and tapped for optics mounts, and the 500 series is mil-spec compatible with a vast ecosystem of accessories—no gunsmithing required for most popular upgrades. You can tailor it to your exact needs without specialized tools.

Pros & Cons
The Advantages: True left-handed operation eliminates ergonomic compromises. Mossberg’s proven action is one of the most trusted in the world. The 18.5″ barrel strikes the perfect balance between maneuverability and control. The price point of $381.82 is highly competitive for a dedicated left-hand tactical shotgun. Its simplicity means extreme reliability and ease of maintenance.
The Trade-offs: As a pump-action, it requires deliberate manual cycling, which demands practice to master under stress. The synthetic stock, while tough, may not have the aesthetic appeal of wood. The cylinder bore is ideal for buckshot and slugs at close range but is not suited for longer-range shooting with birdshot.
Who This Is For
This shotgun is for the left-handed homeowner who demands a no-nonsense defensive tool. It’s for the shooter tired of adapting to right-handed controls or getting hit in the face with brass. It’s also a solid choice for a right-handed shooter who prefers left-side ejection to keep the working action in their field of view. If your priority is a straightforward, dependable, and affordable platform for protection, this is your workhorse.
Frequently Asked Questions
Q: Is this a true left-handed shotgun, or just a right-handed model?
A: This is a true left-handed configuration. The shell ejection port is on the left side of the receiver, and the action release lever is positioned for left-handed operation. The safety is ambidextrous.
Q: What ammunition is best for home defense with this shotgun?
A: For defensive use, we recommend 00 buckshot (9-pellet) or #1 buckshot in 2 3/4″ shells. The cylinder bore will provide effective patterns at room-distance ranges. Always pattern your chosen load to understand its performance.
Q: Can I add a pistol grip or a different stock?
A: Yes. The Mossberg 500 uses a standard stock attachment system. Many aftermarket stocks and pistol grips from brands like Hogue and ATI are drop-in ready, allowing you to customize the fit and feel. Remember, FFL transfer required for firearm purchases.
