9MM VS 40 - GLOCK 19 VS GLOCK 23
This guide details a ballistic penetration test comparing 9mm and .40 S&W calibers using Glock 19 and Glock 23 handguns, respectively. The test, conducted by firearms content creator Edwin Sarkissian, involved shooting through 17 sheets of 24-gauge sheet metal. The results showed surprisingly similar penetration depths for both calibers, with both rounds being stopped by the 12th sheet. A bonus test with a .22 LR round demonstrated significantly less penetration.
