The Virginia Tech massacre occurred on April 16, 2007, on the campus of Virginia Polytechnic Institute and State University in Blacksburg, Virginia, United States. The shootings done by Seung Hui-Cho left 33 dead(including the perpetrator) and 23 Injured. The weapons used are a Glock 19 and a Walther P22, both are semi-automatic pistols.
- The Glock 19 is a compact version of the Glock 17
- Made to be compatible with factory magazines from the older Glock models.
- Short recoil action
The barrel and slide recoil together for only a short distance before they unlock and separate. The barrel stops quickly, and the slide continues rearward, compressing the recoil spring and performing the automated extraction and feeding process. During the last portion of its forward travel, the slide locks into the barrel and pushes the barrel back into battery.
- Muzzle velocity of 375m/s
- Effective range of 50m
- Resembles the Walther P99 but it is somewhat smaller
- May be fired double action with 12 pounds of force, slightly more than 5 pounds of force as a single action.
- Blowback action
Cho also bought jacketed hollow-point bullets, which result in more tissue damage than full metal jacket bullets against unarmored targets by expanding upon entering soft tissue.
