Item Description
Bryant Ridge Co. is pleased to present this ULTRA RARE & DESIRABLE semi-automatic pistol today for a penny-start auction; this is the AMT Automag IV with the RARE Extended 8 5/8" Barrel and chambered in 10mm Magnum!
The AMT AutoMag IV chambered in 10mm Magnum with the extended 8 5/8" barrel is considered an exceptionally rare variation because it represents one of the least common configurations in the AutoMag IV family. Most AutoMag IV pistols encountered today are chambered in .45 Winchester Magnum, while the 10mm Magnum version was produced only for a short time before the model shifted more heavily toward .45 Win. Mag. The 10mm Magnum cartridge itself was an obscure, high-performance round, so demand was limited and production numbers were never large. The extended 8.625" barrel is also specifically associated with the 10mm Magnum configuration, giving the pistol a much more distinctive and specialized profile than the shorter .45 Win. Mag. examples. With limited production, an unusual chambering, stainless construction, and direct ties to Harry Sanford’s AMT magnum semi-auto legacy, this variation stands out as one of the most desirable and difficult-to-find AutoMag IV pistols.

Bryant Ridge's Analysis:
The AMT AutoMag IV is a powerful and highly distinctive magnum semi-automatic pistol from AMT — Arcadia Machine & Tool, a company best known for producing unconventional stainless-steel handguns with bold, performance-driven designs. As part of the AutoMag family, the AutoMag IV followed the legacy of large-frame semi-autos built around high-pressure, hard-hitting cartridges rather than standard service calibers. Its oversized stainless construction, unique profile, and connection to Harry Sanford’s AMT lineage make it an immediately recognizable pistol to collectors of unusual American semi-automatics. This example is especially desirable when chambered in 10mm Magnum, as that chambering is far less commonly encountered than the later and more frequently seen .45 Winchester Magnum AutoMag IV pistols. The 10mm Magnum was an intense, high-performance cartridge that never saw broad mainstream adoption, which kept production demand limited and made surviving examples much scarcer today. When paired with the extended 8 5/8" barrel, the pistol takes on an even more specialized target/hunting-style profile, offering a longer sight radius, greater forward weight, and a commanding appearance that separates it from ordinary semi-automatic handguns. For collectors, an AMT AutoMag IV in 10mm Magnum with the extended barrel represents one of the rarest and most interesting variations in the AutoMag IV family. It captures the spirit of AMT’s willingness to build powerful, unconventional pistols during an era when magnum semi-autos were gaining attention among enthusiasts. With its scarce chambering, limited-production background, stainless construction, and unmistakable AutoMag styling, this pistol stands as a standout collector piece for anyone interested in rare AMT firearms, magnum semi-automatic pistols, or unusual late-20th-century American handgun design.
