Weighing in at roughly 7.5 pounds, the Dickinson Commando Marine has a solid, authoritative feel without being unwieldy. The 18.5-inch barrel is the legal minimum for a non-NFA firearm, making this shotgun highly compact. Its synthetic stock is impervious to the elements, and the marine finish is your first line of defense against the wear of a damp safe or a vehicle mount. This is a tool that fits out of the box and is ready for duty with minimal fuss. The price point of $245.80 makes it an accessible entry into dedicated defensive shotguns.
Who This Shotgun Is For
This shotgun is for the practical defender who prioritizes function over flash. It’s for the Missouri homeowner in a humid climate who needs a reliable bedside option that won’t succumb to condensation. It’s for the recreational shooter who wants a durable, low-maintenance shotgun for the truck or cabin. It’s also an excellent first defensive firearm—the manual action teaches fundamentals and builds confidence with every pump. If your scenario involves potential exposure to moisture and demands a simple, intimidatingly effective tool, this is your candidate.
Pros & Cons
Pros: Exceptional corrosion resistance for long-term storage in non-ideal conditions. The pump action is supremely reliable with virtually any ammunition. The compact size makes it easy to handle and store. It’s a straightforward platform—no complex controls or batteries required. The cost is a major advantage, offering serious capability without a serious investment.
Cons: Pump-action shotguns require practice to master under pressure; short-stroking the action is a real possibility for the untrained. The 4-round capacity is standard but less than some extended-tube alternatives. Aftermarket support for Dickinson-specific models can be more limited than for Remington 870 or Mossberg 500 patterns, though many standard accessories may still fit. That said, for its core purpose, it delivers.
Frequently Asked Questions
Q: Is the marine finish just for looks, or does it actually work?
A: It’s functional. The electroplating process provides a genuine protective barrier against rust far superior to standard bluing. It’s ideal for coastal areas, humid climates, or any environment where metal is exposed to moisture.
Q: What kind of ammunition can I use in this shotgun?
A: You can safely fire any 12-gauge ammunition marked 2 3/4″ or 3″ in length. This includes target loads, buckshot (like Federal FliteControl or Hornady Critical Defense), and rifled slugs. Always start with a box of standard buckshot to ensure reliable function before relying on it for defense.
Q: Can I add a light or other accessories?
A: Yes. The shotgun features a standard barrel with a bead sight and a synthetic forend. Many universal shotgun accessory mounts, such as barrel-clamp style light mounts or saddle shell carriers, will work. For a dedicated light, models designed for Mossberg 500/590 forends may require fitting but are often compatible. Remember, adding weight changes the handling dynamic.
