Some History
The AutoMag (one word) was the brainchild of Harry Sanford, the man also behind the Auto Mag (two words) in the late 1960s. The AutoMag series was produced by AMT / IAI from the late 1980s through the 1990s before the company went under.
Currently, High Standard produces the AutoMag II. The AutoMag series included the AutoMag II, the AutoMag III, the AutoMag IV and the AutoMag V.

AMT AutoMag IV Features
Light Trigger Pull
The AMT AutoMag IV features a light trigger pull, usually around 4 to 5 pounds, making it great for accurate shooting and quick follow-up shots. It’s designed to enhance overall performance, but it’s not without its quirks. The lighter pull means you’ll need to be extra mindful to avoid unintentional discharges, and some shooters find the trigger feels a bit spongy, which can make the break feel less predictable.
Solid Accuracy
The AutoMag IV often delivers tight groupings at 25 yards or more. Its 6.5-inch barrel and the powerful .45 Winchester Magnum round work together to give it some serious precision. That said, it’s not all smooth sailing. Some users have reported reliability issues like jams or misfeeds, especially with certain ammo types. These hiccups can be frustrating and might affect consistency in different shooting conditions.
Stainless Steel Construction
The AutoMag IV’s stainless steel construction makes it incredibly durable and resistant to corrosion, while also giving it that polished, eye-catching look. It’s built to last, but there’s a trade-off. The steel adds significant weight, clocking in at around 50 ounces. This heft can lead to fatigue during long shooting sessions or while carrying it. Plus, while the stainless finish is stunning, it does need regular cleaning to keep it free from spotting or tarnish.
Final Thoughts
We like the AMT AutoMag IV for its powerful .45 Win Mag chambering, and its old-school, bold personality. It’s not perfect, though. The weight and somewhat dated design might not appeal to everyone, and finding parts can be a challenge. But if you’re after something unique that’s both a conversation starter and a powerhouse at the range, this is a gun that delivers on both fronts. It’s not for everyone, but for the right person, it’s a piece of history worth owning.
