I was at the range yesterday with a buddy of mine that's an active duty 1st LT in the USMC. I brought a Level IIA kevlar soft body armor panel with me. It's composed of 12 layers of Kevlar.
We tested it against all of the following rounds and pistol combos:
9mm:
Sig P228 firing Corbon 115gr+P Sierra JHP: No penetration
HK P7 firing Buffalo Bore 115gr+P+ Montana Gold match HP: Full penetration (jacket was shed in the kevlar)
10mm:
Glock 29 firing Nosler 180gr JHP: No penetration
.45ACP:
Colt Government 1911A1 firing Winchester 230gr Ranger SXT JHP: No penetration
5.7x28mm:
FN Five SeveN firing FN SS197SR 40gr Vmax: Penetrated 10 of 12 layers, severe backface deformation of panel.
FN Five SeveN firing FN SS195LF 28gr OTM(1900fps): Complete penetration
FN Five SeveN firing FN SS192 28gr OTM(2100fps): Complete penetration
............
After those tests the panel was still in use-able condition, so we decided to ramp up the tests. We folded it in half, giving 24 layers of Kevlar. Approx threat level would be IIIA.

FN Five SeveN firing FN SS195LF 28gr OTM(1900fps): No penetration
FN Five SeveN firing FN SS192 28gr OTM (2100fps): Full penetration
............
Hugely impressed that the SS192 was able to penetrate 24 layers, we decided to really put it to the test, and folded the panel over on itself again. 48 layers of Kevlar. The rough equivalent to two Level IIIA panels stacked.

And the FN stuff is downright wimpy compared to the Elite ammunition i have on order.
All i can say is ......Dayum.

HK P7 and Buffalo Bore 9mm+P+ 115gr MGM JHP, hole is visible just to right of the bullet.
FN Five SeveN and SS192. Several holes are visible.
As for the panel, i took it apart, offset the layers so none of the holes lined up, and then duct taped it all together as a packet, and threw it in the rear threat panel pocket of my US Armor Level IIIA vest. Hey, it stops .45 acp, so why not, right?
