This ammo will shred a 3a vest. - Liberty Ammunition Civil Defense 10mm Auto 60 Grain Fragmenting Hollow Point Brass Cased Centerfire Pistol Ammunition

The reason i wrote this review was it does what it says. Everyone else's review were absolutely correct. It is lighter and ballistic gel test will tell you of the damage and wound cavities. But you wanna know about 3A armor tests. I bought a new vest because my old was old. Me and my buddy went to a private range and I used a 5 gallon bucket with an old 3A plate, and my brand new Glock 20 Gen 5. We tried Blazer 180 gr FMJ, Underwood 115 gr solid monolith, and Liberty Ammo 60 gr hollow point. First, Blazer, third, Underwood. Both were able to stop a round. But the second round, i went through the plate and punched a hole through the 5 gallon bucket full of water. I thought for sure it was just an old plate, I will use another old plate. I used three shots with Liberty ammo. It punched all three rounds though the plate, no f***ing problem. I puched 2 more rounds, same thing. I was SO impressed. I thought for sure the pistol round that could defeat a vest would be 5.7×28 lead free rounds. I was SO WRONG! The 5.7 rounds are a pretty small round, between 27-40 grain. The hole from the bucket was pretty large. I really wanna see if the Liberty 70 grain will perform the same target. I have 2 old side panels, and will try those.

So two things about 10mm firearms and ammo: 1) You can take out a bear pretty easy. 2) You can take out a 3A vest pretty easy. My Glock 20 is my new carry gun instead of my PSA Rock.
