Gorilla Silverback, 9MM 90gr, Lehigh Xtreme Defense Ammunition – 20 Round Box

This 9mm load features a Lehigh 90gr Xtreme Defense projectile that was designed to be near barrier blind while creating a massive permanent wound cavity. The Xtreme Defense ammunition has an optimized nose flute, total weight, and velocity to achieve a penetration depth range of 18 inches with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollowpoint comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet, it is near barrier blind, ignoring wallboard, sheet metal, and automotive glass. As you probably guessed the Silverback line of ammunition is manufactured with the same incredibly precise loading and inspection process that results in consistency and accuracy unparalleled in the industry. Our ballisticians have tuned this 9mm load to perform well in today’s most popular firearms.

    Gorilla is one of my two favorite ammo Companies and are used in all my EDC and home defense handguns and Q and Noveske 300 B/O in Subs and Supers. Explosive contact! Micah????

    I’m extremely picky with ammo, when I say I have owned everything (9mm self defense) I mean I have owned them all. I like to stack different brands(2 maybe 3 brands )in my home & carry gun magazines. These are my 2nd favorite, these are devastating, and I have them as my EVEN count in my mags. They’re great for going through things that are harder to go through, and chew up anything in their way.
    PS: My favorite is Liberty Defense 50 grain
    2,000 fps with 450 ftp of Energy and are made with 3 pieces instead of regular ammo Thst is made of Brass/lead.
    But if you are on the fence these Gorilla Xtreme cutters are worth every penny, and cycle in everything, I Personally carry Sig P365X and Home is a Glock 19 Gen 5 and s Sig MPXK. And I have Never had a failure to feed or eject EVER!! Which means a lot to me.

    Bought these to use in my new shadow systems cr920p. I was a little concerned about such a light bullet working in a compensated sub compact but they ran like a raped ape.

    I haven’t had to use these in a defensive situation and hope not to bit I have no doubt they would perform as intended.

    I’m getting ready to order a case of their subsonic 300bo for my honey badger I liked this so well.

    Works like a charm, dropped a 8 point at 40 yards. One shot from a 9mm this stuff works
