The .40 SW: A Caliber at a Crossroads - Is It Still Relevant

The world of handgun calibers is constantly evolving, driven by technology, trends, and practical experience. Few cartridges exemplify this rollercoaster ride better than the .40 Smith & Wesson. Once the darling of American law enforcement, the .40 S&W now finds itself at a crossroads, with many asking a poignant question: is it a dying caliber?

Born from the aftermath of the 1986 FBI Miami shootout, the .40 S&W was designed to be the perfect balance: offering the bullet diameter and stopping power of the .45 ACP in a cartridge case small enough to fit into 9mm-sized pistol frames. For decades, it succeeded. Police departments across the country adopted it, and it became a hugely popular choice for civilian self-defense.

However, the landscape has dramatically shifted. The consensus among shooting experts and enthusiasts, as seen in lively online forums, points to a significant decline. The primary reason? The dramatic improvement in 9mm ammunition. Modern 9mm defensive hollow points have closed the performance gap that once made the .40 S&W so appealing. Today's 9mm rounds offer exceptional terminal ballistics, making the power advantage of the .40 much less decisive.

This has brought the .40 S&W's trade-offs into sharp focus. The caliber is known for its "snappy" recoil—sharper and less manageable than the 9mm's push. This can lead to slower follow-up shots and reduced accuracy for many shooters. Furthermore, .40 S&W ammunition is typically more expensive, and pistols chambered in it hold fewer rounds than their identical 9mm counterparts. As a result, many law enforcement agencies are now standardizing on 9mm, creating a surplus of used .40 caliber pistols on the market.

So, is the .40 S&W dead? Not quite. It remains a potent and effective self-defense round. For the savvy buyer, its decline in popularity presents an opportunity. The market is flooded with affordable, high-quality used police trade-in .40 S&W pistols. It occupies a unique niche for those who want more punch than a 9mm but aren't ready to step up to a .45 ACP.

In conclusion, while the .40 S&W may no longer be the king of the hill, it is far from obsolete. Its story is a testament to how innovation can reshape the market. For shooters on a budget or those who simply appreciate its characteristics, the .40 S&W still holds a relevant and powerful place in the holster.
