Heavy & Fast!...Good AMMO For Micro 9MM Self-Defense?
This video tests Underwood's 147-grain Plus P Plus 9mm Gold Dot ammunition through two different barrel lengths: a 3.1-inch Canik Mete MC9 and a 4.5-inch Glock 17. The tests include chronograph readings and gel block performance analysis. The instructor concludes that this heavy, fast ammunition performs well even from shorter barrels, offering significant expansion and penetration.
