This video provides an expert analysis of a craft-made North Vietnamese 1911 copy. The presenter, Ian McCollum, highlights significant mechanical deviations, including a non-functional safety and a dangerous straight blowback action instead of the standard locked breech. The video serves as a cautionary examination of improvised firearm manufacturing, emphasizing the inherent risks associated with such designs, particularly in .45 ACP.

This video reviews 'Firearms Anatomy Book III: The Remington Double Derringer,' which offers insights into firearms design principles rather than just a specific model. Author Ian McCollum highlights the book's value for aspiring designers, covering potential design flaws, safety features, and fundamental mechanical concepts. It's recommended for both professional and amateur designers, including those working with 3D printing.

This review provides an expert look at the Dan Wesson DWX Compact, a highly anticipated carry pistol. It highlights the unique blend of M1911 and CZ 75 design elements, innovative mechanical features like the Sig Sauer-style barrel lockup, and practical ergonomics for concealed carry. The assessment covers range performance, sights, and magazine capacity, offering valuable insights for firearm enthusiasts and potential buyers.

This video explores the history of trigger-based safety mechanisms, demonstrating that the technology is not a new invention by Glock. By examining an Iver Johnson firearm from the turn of the century, the presenter shows a similar trigger safety lever design that predates modern firearms by over 100 years. This highlights how contemporary firearm designs often build upon or reintroduce concepts from earlier eras.

This guide details the field stripping process for the AMT Automag IV, highlighting its Browning-style short recoil action with a tilting barrel. It emphasizes the unique design considerations for its magnum caliber, including an extended chamber. The information is presented with the authority of Ian McCollum from Forgotten Weapons, known for his deep dives into firearm history and mechanics.

This entry details the unique 6-lug rotating bolt mechanism of the 1891 Fosbery Pump Shotgun, as explained by firearms historian Ian McCollum. It highlights the advanced design for its era, predating modern AR-15 bolt technology, and its historical context within firearm innovation. The shotgun's lack of commercial success due to prevailing preferences for break-action designs is also noted.
