9mm vs 40 vs 45: Can’t Believe The Results
This video compares 9mm, .40 S&W, and .45 ACP through various barrier tests including lumber, sand, and concrete, alongside ballistics gel testing. While all calibers performed similarly through most barriers, the .40 S&W showed slightly better penetration and expansion in ballistics gel. The host ultimately favors 9mm due to its lower recoil and higher capacity, despite the .40 S&W's respectable performance.
