For home defense, 9mm is generally considered the better choice over .40 S&W for most people. Here's why:

1. Recoil and Control

• 9mm has less recoil, making it easier to control, especially for follow-up shots and for shooters with less experience.

• .40 S&W has a snappier recoil, which can affect accuracy and speed in high-stress situations.

2. Capacity

• Most 9mm handguns offer higher magazine capacity than .40-caliber counterparts, often by a few extra rounds.

3. Ammunition Cost and Availability

• 9mm is cheaper and more widely available, making it more practical for training and stockpiling.

4. Terminal Ballistics

• Modern self-defense 9mm ammo (like Federal HST, Speer Gold Dot, or Hornady Critical Defense) offers comparable stopping power to .40 S&W with less recoil and more capacity.

5. Wear and Tear

• .40 S&W tends to be harder on firearms due to higher pressures, potentially shortening the life of the gun.

Conclusion:

9mm is usually the better all-around choice for home defense due to ease of use, higher capacity, and good ballistic performance with modern ammo. That said, if you’re already comfortable and proficient with a .40, it's still a viable option.
