In the early 1990s, the Austrian gun manufacturing company Steyr Mannlicher International began development of a polymer-framed, striker-fired pistol intended for military, police and personal-protection applications. Its first version of the pistol, the M9, chambered to fire the 9 mm Parabellum cartridge, was officially released in 1999. The M9 (the M demarking the pistol as having a 4-inch barrel and a 17-round magazine), was soon followed by the M40 in .40 S&W and the M357 in .357 Sig. The lineup continued to expand with the addition of compact S versions fitted with 3.62-inch barrels and shorter grip frames.
I bought a new Pistol a few weeks ago at the KC Gun Show. Steyr S40-A1.
I was looking for a gun that was lighter than my Star 40, and was more comfortable in my hand than my Glock 23. I feel I have found the best of all worlds!
I have ran a little over 600 rounds through it, absolutely no problems what so ever with the gun. And at the end of the day, my hand is still feeling great.
