Big SPEED and POWER From 9MM!
This video details a ballistics test of Underwood loaded 9mm +P+ ammunition featuring 115-grain Nosler jacketed hollow points. The test compares performance from a 3-inch Taurus GX4 and a 4.5-inch P80 (Glock 17 equivalent) through a clothing barrier and into ballistic gel. The ammunition demonstrated significant velocity and expansion, with the longer barrel yielding higher speeds and slightly deeper penetration.
