Back in the 90s when the PS90 and the 5-7 came out I was really enamored by this platform... but 30 years latter the conclusion is that the 5.7x28mm round is a really crappy round. Ballistically the round showed some promise as a body armor defeating round but then came NIJ III+. In a pistol this round is interesting because of the high capacity that is possible but the cartridge length makes it unsuited for mag wells in the grip of a pistol. In a rifle or SBR the round is under powered and has shit for energy at range...

They tried to make one round that could do it all... and ended up with one round that does nothing well.
