Underwood Ammo 139 9mm+P 147gr Jacketed Hollow Point 20 Per Box/10 Case

Underwood Ammo standard Jacketed Hollow Point rounds are unrivaled. We use the Nosler Assured Stopping Power (ASP) projectiles, which feature deep skives designed to create a versatile handgun bullet for use in a variety of applications. The deep skives enhance the expansion characteristics of the ASP bullet without sacrificing accuracy and reliable feeding. The skives in the jacket mouth create precise reliefs in the jacket, which allow for rapid, consistent, reliable expansion. This reliable expansion assures energy transfer and stopping power while limiting the likelihood of over-penetration.

Nickel-plated brass casings, our nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel-plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.

As with all of Underwood Ammo rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
