Turning your 9mm into a 10mm, the old fashioned way.
This video explores the history of the 41 Action Express (41 AE) cartridge, a .40 caliber round designed to be fired from 9mm pistols with conversion kits. It discusses its rebated rim design, which allowed for compatibility with 9mm magazines, and its status as a predecessor to the 40 S&W. The content compares the ballistics of the 41 AE with the 10mm and delves into the cartridge's brief but interesting lifespan in the late 80s and early 90s.
