GENERAL DESCRIPTIONThe GLOCK Safe-Action self-loading pistol, with no-compromise design, combines virtually all the
features demanded of the modern handgun of today - and tomorrow :
· Extreme low overall weight
· High Magazine capacity
· Maximum possible safety for the user
· Outstanding performance characteristics, combining advanced methods on manufacture with
top-quality materials
The weapon is a mechanically-locked recoil-operated pistol with automatic firing pin and trigger
safety as well as Safe-Action trigger safety and Safe-Action trigger system.
Each round is automatically loaded until the magazine is empty. The slide (1) will the remain in the
open position, held by the slide stop lever (27).
MAIN FEATURESThe new Safe-Action trigger system offers the shooter the possibility getting off every shot
quickly and without having to operate externally safety devices
The firing pin (5) is automatically put under partial tension after each round and is fully secured.
There is no risk of an accidental discharge due to dropping the loaded weapon or dues to shaking.
The pistol can only be fired by deliberately pressing the trigger (26). To do this the trigger
finger must actuate the trigger safety. Discharge of a shot by off-centre, sideways pressure on the
trigger is impossible.
The slide stop lever (27) and the magazine catch (19) are easily operated with shooting hand.
The receiver (17), made of plastic with hardened steel guides, has the outstanding features of
ideal dimensions, ideal receiver angle and low weight. 
						

							The weapon has passed the most stringent military and/or industry tests and is regarded as an
absolutely top-class product.

							FUNCTION OF THE WAEPON1) State of the weapon: loaded, i.e., a round in the barrel, firing pin (5) partially tensioned and
secured, trigger (26), in the foremost position. the trigger safety integrated in the trigger is actuated
with the trigger finger in order to pull the trigger all the way.
2) When the trigger slack is taken up to the first pressure point (travel 5mm) the weapon is released
from safety, i.e. the trigger bar lies behind the safety ramp, the firing pin is under tension. As the
trigger is pulled further back, the trigger bar releases the firing pin by means of the connector (24).
The recoil impulse moves the slide (1) backwards. After about 3mm movement to the rear, the
locking action between the barrel (2) and the slide (1) will be released, the barrel swings downwards
over the locking block (22) and is retained in this position. The slide moves back into its final
position on its own. During this return travel the cartridge is pulled out of the barrel by the extractor
(11), and is then thrown out to the right via the ejector (23). The ramp in the slide rails actuates the
connector and separates it from the trigger bar. This causes the trigger bar to be raised by the
trigger spring (25) and to be brought back into the path of the firing pin nose.
3) The recoil spring now brings the slide forwards.
And this happens:
- The trigger bar is pushed onto the safety ramp by the firing pin,
- The firing pin safety is brought onto engagement
- The firing pin  is put under partial tension
- A round is passed out of the magazine, and
- The barrel is locked with the slide
The weapon is again secured and ready to fire After the last round has been fired, the slide will
be held in the open position by the slide stop lever (27).

							SAFETY DEVICESThe weapon has no externally located safety devices which need to be actuated separately. All the
safety or safety release devices function automatically.
1. TRIGGER SAFETYThis is incorporated into the trigger (26) in the form of a lever, and in the untouched state blocks the
trigger from being moved backwards. If the weapon is allowed to drop, or if the trigger is subject to
an off centre, lateral pressure, it is still impossible for a shot to be fired. This safety can only be
released by the trigger being pulled by the trigger finger. This situation offers maximum possible
firing readiness combined with maximum safety for the user.
2. FIRING PIN SAFETYIn the secured position a spring-loaded pin (9) projects into the firing pin cut-out, and blocks it. This
safety is only released when the trigger is pulled back.
3. SAFETY FUNCTION OF THE TRIGGER MECHANISM HOUSINGThe firing pin (5) pushes the trigger bar onto the safety ramp under the influence of the firing pin
spring (7). There is no possibility in this position of the firing pin being released.
SIGHTSThese consist of a rear sight (16) and a front sight (16a), in which white contrast elements are
inserted. The rear sight is adjustable horizontally by displacement, while, for height adjustment. 3
different rear sight heights are available (0.4mm or 0.8mm above or 0.4mm below the normal height).
LOADING AND FIRING1. The magazine is filled by each individual round being pushed into the magazine from the front,
with the base of the round being pressed down first against the pressure of the magazine
spring. If using the factory supplied loading support, slip support over the magazine and place
magazine on a solid surface. Hold loading support firmly and place thumb on top of loading
device: Press down loading device against tension of magazine spring and, while keeping
support down, insert a round as far as possible. While pressing round downwards, slide support
upwards (release magazine spring) and the round will slide into its rest. Repeat operation for
subsequent rounds.
2. Introduce or insert the magazine into the magazine shaft until the magazine catch engages fully 
						

							3. Pull back the slide with free hand, and allow it to spring forwards into the final position. The
trigger finger of the shooting hand remains outside the trigger guard. The weapon is now
secured and ready to fire.
4. After the last round has been fired, the slide remains open. Remove the empty magazine from
the weapon by pushing the magazine catch (19). Insert a new magazine and then either push
the slide stop lever (27) downwards (see photo), or pull the slide slightly backwards and allow it
to spring forwards. The weapon is now again secured and ready to fire.
UNLOADING1. Remove the magazine (see photo).
2. Pull slide (1) back to eject the round which is in the barrel (2).
3. Check to ensure that there is no round in the barrel
4. Allow the slide to spring forwards and pull the trigger into the full pulled position.
DISMANTLING AND REASSEMBLING1. For normal cleaning, it is sufficient to dismantle the weapon into its MAIN COMPONENT
PARTS
– slide (1)
– barrel (2)
– recoil spring assembly (3)
– receiver (17)
– magazine
2. For maintaining and cleaning the weapon, it is recommended that the cleaning equipment
provided as part of the accessories be used, together with the cleaning wadding and special
gun greases and oils available from specialist dealers.
3. The GLOCK pistols are stripped into the main component parts in the following order:
– removing the magazine
– checking safety (ensuring there is no round in the barrel)
– pulling trigger right back
– removing barrel from slide. Before the slide and the receiver are dismantled any further,
attention is drawn to the safety and guarantee conditions. 
						

							4. Removal of the slide (see photo) is carried out as follows:
– Grasp the pistol in the right or left hand in such a way that four fingers rest over the slide and
the thumb rests on the rear side of the receiver.
– Using the fingers draw back the slide (1) about 3mm
– Pull the slide lock (21)
– Push the slide forwards and separate it from the receiver.
If the slide is drawn back too far (more than 3mm), the trigger will move to the foremost forward
position. The slide will then not separate from the receiver (17). Do not use force. The trigger
must first be pulled all the way back.
5. Removal of the barrel (see photo) is carried out as follows:
– Push the recoil spring assembly (3) somewhat forwards with the thumb and raise it
– Take the recoil spring assembly out of the slide (see photo 4).
– Grasp the barrel on the barrel locking piece, push it slightly forwards, raise it and pull it
backwards out of the slide. Reassembling the GLOCK pistols is carried out in the reverse
order to the above.
SAFETY AND GUARANTEE INSTRUCTIONS1. If the weapon is dismantled by the purchaser or by any third parties further than described in
this user’s instruction, and if, as a result of inappropriate handling or incomplete reassembly,
damage or malfunctions are caused, as a result of which the safety devices are rendered
ineffective, then the purchaser shall forfeit ant claim to guarantee against damages thereby
incurred to persons or property.
2. Any change to the basic construction of the weapon, in particular by the circumvention of the
safety devices, is strictly prohibited for safety reasons, and precludes the use of the weapon.
3. The following actions are not permitted on the weapon since they could lead to damage:
– With the weapon unloaded the trigger (26) shall not be manually brought into the foremost
position and actuated. The trigger shall only be brought into its foremost position by pushing
back the slide (approx. 15mm or more)
– Should, with the slide disassembled, the trigger (26) be inadvertently brought into its foremost
position, then the trigger shall be only actuated when, at the same time, the triggerbar is
pushed forward (in muzzle direction). 
						

							– With the slide removed, it is not permitted to tension and spring the firing pin (5) forward,
since this could damage the firing pin safety.
– The steel insert located in the cover platte (15) to the slide must not be removed.
4. No liability whatever can be accepted if inexpertly manufactured or inexpertly filled ammunition
is used.
All liability whatever is excluded in the event of these instructions not being observed.
CHECK OF SAFETY DEVICES
The following safety checks are to be carried out at regular intervals, e.g. before each use or
when cleaning the weapon after use:
a) Function testing the trigger safety:
– Remove the magazine from your pistol and reassure that there is no cartridge in the barrel.
Then the trigger may be pulled back.
– Bring back the trigger in its most forward position by cycling the slide. The trigger safety (lever
integrated in trigger) should then be properly engaged.
– When lateral pressure is applied on the trigger the safety should keep engaged, blocking the
trigger movement.
– Failure of the trigger safety to properly engage or block indicates that it is defective.
Do not reload or use your weapon again and contact GLOCK Ges.m.b.H. or an
authorised GLOCK armorer immediately.
b) Function testing the firing pin safety:
– Dismantle the weapon into its main components as described previously and remove the
recoil spring/recoil spring tube and barrel from the slide.
– Hold the slide in a muzzle down position and depress the firing pin safety. The tip of the firing
pin should move forward and be visible protruding from the firing pin hole.
– Keep the firing pin safety depressed and shake the slide. The firing pin should be distinctly
heard moving freely.
– Draw back manually the firing pin about 0.2 in.
– Hold the slide in a horizontal position and push forward the firing pin toward the muzzle, firing
pin safety being engaged. The firing pin should not protrude from the firing pin hole. If it
does, the firing pin and the firing pin safety should be replaced.
