5.7s, especially out of a pistol, are not good self defense guns. Luckygunner did a whole series of gel tests with 5.7s out of pistol, 10”, and 16” barrels to prove it. You either get good penetration with a .22 caliber bullet that doesn’t expand, or you get a bullet that fragments or overexpands and therefore has really shallow penetration. Also, the bullets aren’t going fast enough for the temporary cavity to tear and cause damage, that starts in intermediate rifle round territory (or shit like 460 & 500 S&W) and 5.7 doesn’t travel fast enough.
And if you don’t believe me, no police agencies or militaries that issued 5.7s are ordering more 5.7s. It’s a varmint hunting caliber.
