I'll list some specs to compare them, would like your vote as to which would you buy; primary purpose- CCW.
The most significant differences I've noticed are price and the power of the rounds. The FN 5.7 is approximately $1000 on the street and the PMR is about half that cost. The .22WMR bullet in the PMR is fast, but it's awful light and no match for the 5.7. The .22WMR costs roughly half the price per bullet than the 5.7. Many say the reliability of a rimfire round (.22WMR), is less reliable than a center fired bullet. The 5.7 holds 20 rounds standard, but an extender is available to take up to 30 rounds; whereas the PMR holds 30 rounds in the pistol grip, no extension needed.
The 5.7 seems to be about twice the bullet (power, cost) than the .22WMR.
