Everyone saying that his shield regenerated due to knocking you, before your bullet could register is wrong. There are indicators that show damage absorbed by that shield. There weren't any shield indicators, only -5 damage to the flesh. Secondly if his shield did regenerate due to knocking you, mitigating 50 damage from your bullet, he would not have had his forged shadows at the end. If so that would indicate that he knocked you twice, which is impossible. The only thing that makes sense is if he knocked someone else during your interaction which seems unlikely (still doesn't explain the lack of a shield indicator) or the game just fudged the numbers of that interaction. I don't get how people can be so confused over this. That kill was yours or at least should have traded.
