Weighing in at approximately 7.5 pounds, the TSA Auto balances well for a smooth swing. The 28-inch barrel length is a classic choice for upland game and waterfowl, providing the sight radius and inertia needed for consistent leads. It’s compatible with a wide array of aftermarket chokes using the common Invector-style choke tube system, so you can tailor your pattern for different game or targets. This model is drop-in ready for standard choke tubes from brands like Carlson’s or Trulock, letting you customize without a gunsmith.
Who This Shotgun Is For
This shotgun is built for the active hunter and shooter who values function over flash. It’s for the Missouri waterfowler who spends mornings in a damp layout blind, the turkey hunter navigating brush, and the recreational shooter who wants a reliable auto-loader for clays without a four-figure price tag. If you need one shotgun to cover multiple roles—especially where weather is a factor—this is a serious contender. At $533.44, it delivers core performance where it counts.
Pros & Cons
Pros: The major advantage is the 3.5-inch chamber versatility paired with a soft-shooting gas system. The synthetic stock is practically maintenance-free. The price point is accessible for a full-featured semi-auto. The 28-inch barrel offers a traditional, balanced feel for wing shooting.
Cons: As an entry to mid-level auto-loader, the finish and trigger may lack the refinement of higher-end models. The synthetic stock, while tough, may not fit every shooter perfectly without adjustment. The 5+1 capacity is standard but not exceptional.
Frequently Asked Questions
Q: What shells can I shoot in this 3.5-inch chamber?
A: You can safely fire 2.75-inch, 3-inch, and 3.5-inch 12-gauge shells. Always start with the manufacturer’s recommended loads for break-in to ensure reliable cycling.
Q: Is the barrel threaded for choke tubes?
A: Yes, it uses the common Invector-style choke system. It comes with a set of chokes (typically Improved Cylinder, Modified, and Full), and you can easily find aftermarket tubes from most major manufacturers.
Q: Is it reliable with lighter target loads?
A: The gas-operated system is designed to cycle a range of loads. For optimal function with light 2.75-inch target loads (often 1 oz or less), ensure the gas system is clean and follow the break-in procedure with heavier loads first.
