Safety intercept notch
The safety intercept notch is a passive safety device that prevents the hammer
from falling if the primary sear notch fails. It also prevents the hammer from
hitting the firing pin should you prematurely release the slide or hammer while
cocking the pistol, provided the hammer has moved past the safety intercept
notch. Using the safety intercept notch as a “half cock” position is a misuse of
this feature and can result in unintentional discharge of the pistol and/or dam-
age to the sear.

WARNING
A FIREARM’S SAFETY FEATURES ARE MECHANICAL DEVICES
WHICH ARE NOT A SUBSTITUTE FOR PROPER AND APPLIED
TRAINING IN SAFE GUN HANDLING. YOU AND YOU ALONE ARE
THE ULTIMATE SAFETY MECHANISM. THERE IS NO SUCH THING
AS A “CHILDPROOF” SAFETY OR ONE WHICH CAN COMPLETELY
PREVENT ACCIDENTAL DISCHARGE FROM CARELESS OR
IRRESPONSIBLE USE. NEVER COMPLETELY TRUST ANY SAFETY
MECHANISM.
Thumb safety
The thumb safety is located above and to the rear of the left grip. To operate the
thumb safety, cock the hammer by pulling the slide to its most rearward posi-
tion and release, letting it fly forward with the full force of the recoil spring. The
thumb safety cannot be engaged unless the hammer is fully cocked and the slide
is fully forward. Then push the thumb safety fully upward into the thumb safety
notch (see Figure 2). When engaged, the slide and sear are blocked, preventing
the hammer from falling when the trigger is pulled.
To disengage, depress the thumb safety fully downward (see Figure 3). When the
thumb safety is down, the hammer is free to fall when the pistol is properly
gripped and the trigger is pulled.

Grip safety
The grip safety is located on the rear of the frame. When engaged, the grip safety
blocks the trigger. The user disengages the grip safety by firmly and properly
gripping the pistol.
Disconnector
The disconnector is a passive safety device that engages and disengages automat-
ically during the cycling of the slide. This device disengages the sear while the
slide is moving, thus preventing a round from being fired before the pistol is in
battery.
Firing pin safety lock
The firing pin safety is a passive safety device that locks the firing pin in place
until the trigger is pulled. The purpose of this device is to prevent the firing pin
from moving and helps prevent accidental discharge as a result of the pistol
being dropped.
