The CCI 22 WMR rounds they recommend are $10-13 for 50 rds and the FN 5.7 x 28 go for $19-23 for 50 rds where I live. They are relatively powerful and I enjoy shooting my 22 Mag revolver. At an average cost of $500-550 it is an expensive plinking gun. The 57 is quite powerful & effective for its small caliber but at around $1100 is quite pricy for what you get. It is a great sidearm for the P90 AR. I believe that the PMR-30 was designed to be a poor man’s FN 57.
The P90 AR is so small it doesn't need a separate sidearm! LOL!

OK, so the price difference for ammo isn't as big as I thought, which is good. Though as you point out, the difference in weapon price is also double.
What sort of usage does the FN 5.7 enable that the PMR-30 can't match?
