This was a very educational article, and it makes me think best protection would have to come from something like Dragon scale. This would be a fun, home-guncrafting, R&D project to create DIY Homespun Dragon scale, and there’s very few people with the interest, equipment, materials, and knowledge to go this route. What could possibly work along these lines?. Most success would likely come from a layered approach. The foundation would likely be a type of chain mail, to which overlapping scales were attached. Scales could best be made up of layers of heat-treated sheet-steel, forged into a single scale. This would have a sort of Damascus characteristic, having strength and flexibility. Front and back of steel scale would need layers of ceramic composite added to the Damascus steel, to create a ballistic sandwich,which would be covered in built up anti spall coating. Some concept like this would stand the best chance of defeating armor piercing rounds,provide the highest level of coverage, protection, and mobility. I recall seeinga product only sold law enforcement on the TV series Beyond 2000 years ago.It was tested by a police department with every sort of weapon they have available including a 50 caliber,and was able to defeat them all. I think you can still find reruns online of the Beyond 2000 series,but there are no updates, and who knows what ever happened to this ballistic system?
