About this product
The TR Imports Alpharms Inertia 1 Shotgun is a 12-gauge semi-automatic built around an inertia operating system with a 26-inch 4140 steel drilled barrel. It's designed for straightforward field use and sporting applications, offering a low-maintenance experience with a polymer synthetic stock. This model aligns with Ironclad Armory's ethos of mechanical precision paired with practical, durable design.
What is the TR Imports Alpharms Inertia 1 Shotgun used for?
This shotgun is primarily used for hunting and sporting clays, thanks to its reliable inertia system. With a 26-inch barrel and 3-inch chamber, it handles both light and heavy loads effectively, making it versatile for various game and range scenarios. It's ideal for shooters who prioritize simplicity and dependability over customization.
How does the TR Imports Alpharms Inertia 1 Shotgun compare to the Stevens 555 Sporting O/U 12 Gauge 30in?
The Alpharms Inertia 1 outperforms the Stevens 555 in semi-automatic reliability versus the over-under's manual action, with fewer moving parts and faster follow-up shots. However, the Stevens 555 has superior fit and finish with its walnut stock, making it better for traditionalists, while the Alpharms excels in rapid-fire situations. For a detailed breakdown, consider reading our comparison of inertia vs. over-under systems.
What does it weigh and what are the dimensions?
The shotgun weighs 7.2 pounds and measures 46 inches in overall length with the 26-inch barrel. Its synthetic stock reduces weight compared to wood alternatives, aiding in maneuverability during extended use. The barrel diameter is 0.73 inches, contributing to its balanced feel.
Who is this NOT for?
This shotgun is not for competitive trap shooters who require precision-tuned chokes and adjustable stocks. It lacks the fine-tuning features found in higher-end models like the Stevens 555 Sporting, which offers interchangeable chokes and a more refined action. Additionally, those seeking a compact home-defense firearm should look elsewhere due to its length.
What's in the box?
The box includes the shotgun, one Mobil choke tube, a rotative cap, and a basic owner's manual. No additional accessories like slings or cleaning kits are provided, keeping the package minimalist. This aligns with its no-frills design philosophy.
Is the TR Imports Alpharms Inertia 1 Shotgun worth it at $336.99?
At $336.99, it offers solid value for a reliable semi-automatic shotgun with a durable build. It's priced lower than many competitors, such as the Stevens 555, which starts around $800, making it accessible for budget-conscious buyers. However, expect to invest in aftermarket chokes or sights for specialized use.
