A favourite of airsoft players for CQB games, The Firearm Blog TV discusses the FN PS90 whether it is a toy to have fun with or a tool to do some serious work with... "The 5.7x28mm cartridge is certainly a divisive round. On one hand, you have people making ludicrously grandiose claims about its effectiveness, while others simply write it off as a gimmick or overpriced .22WMR from Belgium. A long time ago I wrote the PS90 off as a pointless, but fun rifle (having little utility but being a fun range toy) and decided to run around with it at the ranch for a few different trips up there. So, is it a tool or simply a toy?"
