9MM VS 40 HOLLOW POINTS
This video compares the penetration performance of 9mm and .40 S&W Federal Premium 135-grain hollow point ammunition against sheet metal barriers. Using Glock 19 and Glock 23 handguns, the test revealed minimal difference in penetration depth between the two calibers, with both stopping around the 9th to 10th plate. The results suggest that for these specific loads and barrier types, the perceived differences in stopping power might be less pronounced than expected.
