Quick Answer
The best hollow point caliber for home defense is the 9mm, as it offers a balance of penetration and expansion, making it effective against various targets. It's also widely available and relatively affordable. A good 9mm load for home defense is the 124-grain +P.
Caliber Options and Considerations
When selecting a hollow point caliber for home defense, consider the size and effectiveness of the projectile. A larger caliber, such as .40 S&W or .45 ACP, can provide more stopping power, but may also require more training to handle effectively. The 9mm, on the other hand, balances penetration and expansion, making it a popular choice for self-defense.
Effective Loadings and Penetration
For home defense, it’s essential to choose a load that expands reliably and penetrates to a depth of 12-18 inches in ballistic gelatin. The 124-grain +P 9mm load from Hornady Critical Defense meets these criteria, expanding to 0.75 inches in diameter and penetrating 15.25 inches in gel. This load is an excellent choice for a home defense handgun, such as the Glock 19 or M&P Shield.
Training and Technique Considerations
Regardless of the caliber chosen, proper training and technique are crucial for effective home defense. Practice shooting at various distances and angles, and consider taking a defensive handgun course to learn techniques such as the “2-inch rule” and “contact shooting.” By combining a reliable caliber with proper training and technique, you’ll be better equipped to defend yourself and your loved ones in a home defense situation.
