In terms of defense ammo, the .45 ACP is generally considered to be more effective at stopping an attacker due to its larger diameter and heavier weight. According to data from the FBI, the .45 ACP has a higher one-shot stop percentage than the .40 S&W and .357 SIG, with an average of 95.4% compared to 88.5% and 85.6%, respectively. However, the .40 S&W and .357 SIG have a number of advantages, including a higher magazine capacity and less recoil, which can make them easier to shoot accurately and quickly.
Despite the advantages of the .45 ACP, the .40 S&W and .357 SIG have become increasingly popular in recent years due to their smaller size and lower recoil. Many modern .40 S&W and .357 SIG defense rounds, such as the Hornady Critical Duty and the Winchester PDX1, have demonstrated excellent expansion and penetration in ballistic gel tests, making them well-suited for self-defense applications. According to data from the Hornady website, the Critical Duty .40 S&W round has an average expansion diameter of 0.64 inches and an average penetration depth of 12.5 inches, which is comparable to many .45 ACP rounds. Ultimately, the choice between .45 ACP, .40 S&W, and .357 SIG defense ammo will depend on the individual’s personal preferences and needs, as well as their firearm and shooting style.
