Steyr S9: This is one of a series of medium polymer-framed semi-auto guns in a wide variety of cartridge configurations. Steyr originally introduced the "M" series in the 1990s, then followed up with the slightly smaller "S" series, in configurations for the 9mm, .357 Sig, and .40 S&W cartridges. They have subsequently expanded the line to include "L" and "C" versions. All guns share a very low bore-axis for increased stability and reduced felt recoil. The standard overall size of this design is 6.5".
