This is our defensive 9mm "BLACK LABEL" ammunition. We use factory new brass from "1776 USA", and a 124 grain "Nuke" hollow point bullet from "Rocky Mountain Reloading". The "Nuke" is designed for maximum expansion at lower velocities, which means it will perform well out of shorter barreled concealed carry pistols. At 1,100 FPS it expands to approximately .630 inches. Out of shorter barrels, where it may only reach 1,000 FPS, it expands to approximately .590 inches. Whether you're carrying a full sized pistol or a sub-compact, you can be confident that this cartridge will perform. When you're carrying, carry BLACK LABEL.
