This video from Geauga Firearms Academy provides an expert-level breakdown of handgun calibers for self-defense, emphasizing practical experience over emotional bias. The instructor, Neil, strongly recommends 9mm as the optimal choice due to its balance of capacity, cost, effectiveness, and manageable recoil, while advising against .380 ACP, .40 S&W, and .45 ACP for most self-defense scenarios.
