Is the .40 Really Dead?
The .40 S&W caliber is far from dead, offering a significant power advantage over 9mm in the same frame size. While 9mm is currently more popular, .40 S&W remains widely available and effective for self-defense, with historical roots in law enforcement adoption following the 10mm. Tests suggest .40 S&W provides better penetration and larger wound cavities than 9mm, making it a compelling choice for many shooters.
