There have been more recent tests that show it outperformed the 9mm, less recoil allowed for better and faster grouping. I'll have to double check and see if that was the government armor piercing rounds or the over the counter 5.7. I've read so many pros and cons. Its funny how biased most sources are.. its definitely a love it or hate it situation with the round. I'm not thinking primary gun, but I still want it to work. For $1100 its making me consider it.
Also.. why is the 5.7 pistol so popular if so many people think its basically a .22?
