Is It REALLY That Much BETTER?.....357 Sig vs 9MM +P+ Self-Defense AMMO Test!
This review compares .357 Sig and 9mm +P+ self-defense ammunition using ballistic gel and clothing barriers. The .357 Sig demonstrated superior velocity (1464 fps vs 1237 fps) and energy (590 ft-lb vs 421 ft-lb), resulting in more significant temporary cavity disruption and fragmentation, despite slightly less weight retention. While .357 Sig outperformed 9mm +P+ in testing, its declining market popularity due to industry trends is noted.
