Why 10mm Auto Was a Total Disaster for the FBI

The FBI’s adoption of 10mm Auto in 1990 was supposed to be a revolutionary leap forward for law enforcement. It wasn’t. Today, we’re walking through the factors leading up to the FBI’s infamous decision and why they quickly ditched 10mm in favor of .40 S&W. Find out what went wrong, and the parts played by Smith & Wesson and Gaston Glock. This one is a little longer than normal, and it also took longer to put together than normal. We were going for more of a documentary style, and a lot of effort went into the research, fact checking, and editing. We hope it was worth the wait!
