There's just something about it.
This is the FN Five-seveN. Made as a companion for the P90 and it uses the same 5.7 mm cartridge.
It's kinda sexy too.
The P90 appears regularly on both Stagate SG-1 and Stargate Atlantis: My favourite TV shows.
So if the P90 is good enough for Stargate Command, then it must be good!
