For a couple of years now, Belgium's FN Herstal has been working to secure a significant slice of the American market for law enforcement duty pistols. The Belgian company, which makes the legendary Browning Hi-Power pistol, launched its first polymer police handgun, the FNP-9 (9mm), back in 2006. The FNP is now available in 9mm, .40 S&W, .357 SIG, and .45 ACP.
