under what coated penetrator ammunition

by BigMackTruck, Verified Owner from NV, United States Written on March 8, 2025
The +P+ ammunition along with the design allows the 9mm to pass through windows and other barriers. It is a great ammunition for those wanting penetration and no expansion. I use a second magazine with this ammunition as a backup in case I need ammunition with superior penetration.
