9MM VS 45ACP
This video compares the penetration capabilities of 9mm and .45 ACP using sheet metal tests. The 9mm (115gr FMJ) penetrated 13 discs, while the .45 ACP (230gr FMJ) penetrated 11. Despite less penetration, the .45 ACP caused more violent deformation and larger holes, indicating greater 'punch'. The 9mm's higher velocity and smaller surface area contribute to its superior penetration.
