Home Forums Hunting & Shooting Handguns Don't Drink the 5.7mm Koolaid

First of all, this is the handgun forum, not the "machine gun" forum.
Second, the 5.7 round was designed to shoot through body armor from a handgun. To my knowledge, no 9mm round does that from a handgun.
3rd, try shooting the so called 5.7 FMJ, non expanding, underloaded, practice round into a simple 2.5 gallon jug of water. Then try it with any 115-124 gr. FMJ 9mm round. The results aren't even remotely close. So believe whatever you want. E
