When it came on the scene in the 90's, its claim to fame was shooting through soft body armor. But the cost of ammo and the fact there are better self-defense handgun options; it never really took off. Losing its energy very quickly causing shallow penetration makes it not a popular handgun defensive round.
Theres plenty of information available on it. Like any round its application driven. I just never had the application for it.
