The first external trigger safety acts as the primary fail-safe.
#Steyr mannlicher m9a1 manual#
The pistol has a multi-stage safety system consisting of two automatic internal safeties, two external trigger safeties and a manual lock safety. After expending the last cartridge from the magazine, the pistol's slide remains locked open on the metal slide stop, located on the left side of the frame and operated with the thumb. The magazine catch-release is located on the left side of the frame, directly behind the trigger guard.
The magazine's follower and floor plate are fabricated from polymer. The pistols are fed using a detachable steel magazine of the single position feed type with the cartridges arranged in a staggered column pattern. A locking block integrated into the frame then engages a lug at the base of the chamber and drives the barrel downward, separating it from the slide and terminating any further rearward movement while the slide continues back in a straight line. When fired, the recoil impulse from the ignited cartridge drives the barrel and slide back, locked together until the bullet leaves the barrel and pressures drop to a safe level. The cold-hammer-forged conventional rifled barrel is locked to the slide by means of a single rectangular lug around the barrel chamber that recesses into the ejection port in the slide.

The Steyr M series of pistols employs the mechanically locked Browning short recoil method of operation with a linkless, vertically dropping barrel. The trigger travel is 4 mm (0.16 in) with a pull weight of 25 N (5.6 lb f). Pulling the trigger all the way to the back will compress the firing pin spring completely, draw the firing pin fully to the rear and position the trigger bar to release the firing pin and fire a round. When the trigger is in the forward position, the firing pin spring remains lightly compressed (pre-cocked by the forward motion of the slide as it returns to battery). Hammerless and striker-fired, the Steyr M features a double action only (DAO) pre-set trigger mechanism marketed as a "Reset Action" trigger. The Steyr M series uses a very high grip profile which holds the barrel axis close to the shooter's hand and makes the Steyr M more comfortable to shoot by reducing muzzle rise and allowing for faster aim recovery in rapid shooting sequence. The frame is an injection-molded synthetic polymer and parts of the trigger and striker mechanisms are pressed from sheet metal. The slide is precision-milled from steel and coated in a tenifer finish. Steyr wanted to take advantage of recent advancements in manufacturing techniques.

In 2013, the Steyr M (Medium) and S (Small) form factors were complemented by the L (Large) sized series and the C (Compact) sized series both available in 9×19mm Parabellum and.
These pistols were developed primarily for concealed carry and have a shortened barrel, slide, smaller frame and a reduced magazine capacity. 357 SIG) and two smaller variants of the M9 and M40 designated the S9 and S40 respectively. 40 S&W was developed before the M9, followed later by the M357 (chambered in. Design work on the new pistol began in the early 1990s and the final product known as the M9 (adapted to fire the 9×19mm Parabellum cartridge) was officially unveiled in the spring of 1999.
