Fire power - Doubletap Ammunition 10MM155X Tactical 10mm Auto 155 Gr Barnes TAC-XP Lead Free

Out of a Glock 20 ( 5” barrel ) this ammo fires at 1400 FPS and reaches 683 ft. pounds of energy. It’s a bit hard to imagine a center mass hit requiring a second round to stop any threat be it four or two legged. With the addition of the Barnes Tac Xp round which wildly expands this round will certainly take care of your self defense needs.
