No PS90 or Five Seven seen

Went to the Houston gunshow today and among the many many many guns there were no PS90s or Five Sevens to been seen. Not sure what this means, extremely popular or just hard for vendor to get. I did not even see any PS90 mags for sale.

I did pick this up:

Well of course not this one but one just like it. $580 plus tax. Was not in the market for a Beretta but I really liked the gun. I was going to get a Compact Walther P99 in 9mm but choose the Beretta instead.
