Pistols created since 1912, in the house of Steyr Mannlicher, are famous all over the world for their futuristic design, superb ergonomics, absolute safety, and extraordinary precision. The Steyr M continues to be a polymer framed, double-action-only, striker-fired pistol that is designed for military, law-enforcement, and the civilian market, but the improved A1 series has better ergonomics than previous M-series pistols. The M40-A1's 4˝ barrel is cold hammer-forged with conventional rifling and has a fully supported chamber in all calibers. The pistol comes standard with a double trigger, or trigger within a trigger, that functions as an integrated safety. The trigger design has been upgraded to improve the feel over the older pistols and the crunch and grit of the old trigger has been replaced with a smoother and lighter pull. A Picatinny rail has been added for accessory mounting.
