2.1 Main Features
The WALTHER P99 pistol is a magazine fed, semi-automatic pistol utilizing an
internal striker system to fire the cartridge. Being absent of an external hammer and
the slide having a smooth contour abates the pistol from snagging on clothing when
concealed. The open post sights of the P99 are designed for rapid aiming and target
acquisition. The P99 features a striker status indicator and a loaded chamber
indicator, along with a trigger safety and automatic internal safeties. The frame is
made from high-strength polymer and has an accessory rail incorporated to
accommodate tactical lights and lasers, interchangeable grip-backstraps for varying
hand sizes, and an ambidextrous magazine release integrated into the trigger guard.
The P99 is available with one-sided or ambidextrous slide stop lever.
The P99 offers the choice between Full Size (FS) and Compact (C) frame sizes,
available in either 9mm x 19, 9mm x 21 and .40 S&W. Trigger actions available are
Anti-Stress, Quick-Action or Double-Action-Only.
Anti-Stress (AS): Traditional Double-Action/Single-Action trigger with Decocker.
Quick-Action (QA): The pre-set trigger action with short trigger travel and same
trigger pull from the first to the last round, and Field-Stripping Aid.
Double-Action-Only (DAO): Double-Action Trigger with same trigger pull from the
first to the last round. The striker returns to its de-cocked position after each shot.
The sole function of the trigger on the P99 pistol is to fire the cartridge. It is not
necessary to squeeze the trigger prior to field-stripping.
Details of the different trigger actions will be further explained below and in
section 8 “Technical Specifications“.
2.2 Functional Description
The WALTHER P99 semi-automatic pistol operates on the short recoil, locked-
breech system.
When the trigger is squeezed, the striker is released and the cartridge is fired. The
cumulative gas pressure propels the projectile down the bore of the barrel and out of
the barrel. The resulting impulse causes a rearward movement of the barrel and
slide. The barrel and slide recoil together for a short distance, until the barrel is
unlocked from the slide by the camming action at the lower rear of the barrel. The
breech end of the barrel is drawn downward and the rearward movement of the
barrel it is stopped. The slide continues rearward, extracting the fired cartridge case
from the chamber and ejecting it to the right.
After the slide reaches the limit of its rearward travel, the recoil spring brings the slide
forward again, stripping a new round from the magazine and pushing it into the
chamber. The cycle of fire is completed with the locking of the barrel to the slide. The
trigger must be released and squeezed again in order to fire the next shot.
