"for a friend"..I just got 1000 rounds shipped of the blue tipped 5.7x28 from psa for $359 for a friend. That's a big pistol to conceal though. I don't think the PMR 30 compares to it well at all. The PMR is more of a toy, the FN is a very nice pistol.
Don't be embarrassed, step out of the shadows. Many of us own 5.7 without stigma.
Kidding of course..
