Wake up! 44 Magnum, 454 Casull and 500 Smith&Wesson are all hand guns. All will knock a man off his feet, go through the vest and take out whatever maybe in the bullets path. Vest means nothing, only to the average firearm.

The .500 would probably punch your trauma plate right into your body cavity. May not penetrate, but it won't do you any good as the shock transfer alone would turn your guts to jelly.
