FN-tastic Firearm
My Five-Seven pistol is my favorite firearm. It is without a doubt THE handgun I would have if I had only one. It needs a steady hand but the super-sonic, flat trajectory and round options make it a bridge between "hand guns" and "long guns". Ammo is pricey and the brass doesn't last long but I still take it out once or twice a month...when I take out my other long range guns...

Here's a bit of Wikipedia history.
The FN 5.7×28mm is a small-caliber, high-velocity cartridge designed and manufactured by FN Herstal in Belgium.[7] It is a bottlenecked centerfire cartridge that is somewhat similar to the .22 Hornet or .22 K-Hornet.[7] The 5.7×28mm was developed in conjunction with the FN P90 personal defense weapon (PDW) and FN Five-seven pistol, in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge.[10][11]
In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm Parabellum cartridge.[11] The tests compared the relative merits of the 5.7×28mm cartridge and the 4.6×30mm cartridge, which was created by Heckler & Koch as a competitor to the 5.7×28mm.[11] The NATO group subsequently recommended the 5.7×28mm cartridge, citing superior performance in testing, but the German delegation objected and the standardization process was indefinitely halted.[11]
By 2006, FN's 5.7×28mm firearms—the P90 personal defense weapon and Five-seven pistol—were in service with military and police forces in over 40 countries throughout the world.[12] In the United States, 5.7×28mm firearms are currently used by numerous law enforcement agencies, including the U.S. Secret Service.[13][14]
