I don't agree. While back in the day, the .220 Swift was erratic, it isn't today because we now have much better bullets.
That and you can't get something for nothing. The 5.7 FN kicks 30-40% less than a 9mm which, in turn kicks alot less than a .357 Magnum. The FNH pistol holds 20 rounds and weighs 19 ozs. empty.
I suspect with a decent soft point bullet, that will both expand and hold together, like the .22 rimfire magnum from a handgun, it will do alot jobs. E
