Shot armor panel
Digging through my things, looks like I still have the .45 Magtech FMJ slug and the piece of kevlar we shot a year ago with my FNP-45. This piece of kevlar came from a second chance vest made in the late 80's (Kevlar 29?). The backing was a sandbag. 30 layers overall and not 1 layer penetrated. The black marks on the kevlar are where the bullets landed, we shot this a total of 5 times from both sides. Not a single layer penetrated whatsoever. If you look closely, the slug is a bit dented and the rifling marks from the barrel are visible.
Now this is a .45 ACP, probably a Level IIa-II threat, certainly not IIIa but for what I paid for, this was a neat experience and a good vest.
Sorry for the blurry picture, my only camera is from my phone.
