[QUOTE="Zerstorer, post: 525801, member: 555939"] I call BS [IMG]//content.invisioncic.com/y282845/emoticons/bsflag.gif.21f42eccd34b7d1eb1608fb1b59b69c3.gif[/IMG] on that and will put in a short physics lesson: The force of the projectile is the same as the force exerted on the cartridge prior to ejection, to be technical. Just a hair after the bullet leaves the barrel, the slide starts moving back. (notice how the pull of the recoil spring gets easier after the first .25-.5 inch) The force exerted on the cartridge is now applied to the slide, which has MUCH more mass than the bullet, and uses the spring to absorb most of the recoil. So, the force exerted on the bullet is greatly dissipated by the recoil spring and ejection of the casing. Ever wonder where the force comes to knock the empty case out? Now on to impact: When the bullet impacts, its force is concentrated on a single point. As the nose impacts, it slows down (transferring force) and then the back of the bullet catches up. Depending on bullet type, you get deformation or expansion/fragmentation. One bounces around in the body, the other send little chunks everywhere. Now on to the actual thread subject: 9MM is good and fun! I shoot a Ruger P95 DC. My alltime fav is 7.92 tho... [/QUOTE]
