SAFETY INSTRUCTIONS
Always follow the safety instructions for your safety and the safety of others.
1. Always handle your pistol as if it were loaded.
2. Never point your pistol at anything you do not intend to shoot.
3. Never take anyone's word that a gun is unloaded.
4. Always make sure that your pistol is not loaded before laying it down, or
handing it to another person.
5. Always keep and carry your pistol empty, except when you intend to shoot.
6. Never abuse your pistol by using it for any purpose other than shooting.
7. Never leave your loaded pistol unattended.
8. Before loading your pistol be sure that the barrel bore, chamber, and action are clean
and clear of obstructions. After shooting, clean the dirtied pistol as soon as possible.
9. Always use only clean, dry, original high quality commercially manufactured
ammunition, which is appropriate to the caliber of your pistol.
10. Never drink alcoholic beverages or take drugs before or during shooting.
11. Always wear safety glasses and ear protection when shooting.
12. Always keep clear and keep others clear of the ejection port.
13. Never squeeze the trigger or put your finger in the trigger guard until you are
aiming at a target and ready to shoot.
14. Always be absolutely sure of your target, and the area behind it, before you
squeeze the trigger. A bullet could travel through or past your target up to
several hundred meters.
15. Never shoot at a hard surface such as rock, or a liquid surface such as water.
16. Never fire your pistol near an animal unless it is trained to accept the noise.
17. Never indulge in "horseplay" while holding your pistol.
18. Failure to fire: always hold the pistol, keeping it pointed towards the target, or
a safe open area and wait 30 seconds when the pistol fails to fire. If a hangfire
(slow ignition) has occurred, the round will fire within 30 seconds. If the round
does not fire, remove the magazine, eject the round and examine the primer; if
the firing pin indent on the primer is light, or off center, or non-existent, have
the pistol examined by a competent gunsmith.
19. Always make sure your pistol is not loaded before cleaning, storing or
travelling.
20. Always keep and store your pistol and ammunition in separate locked
receptacles out of reach and sight of children and untrained people.
21. Never alter any parts of your pistol as the safety and proper function of your
pistol could be seriously compromised.

22. Always be aware that corrosion, use of damaged ammunition, dropping the
pistol on hard surfaces or other "coarse treatment" could cause damage you
may not see. If something like this happens allow the pistol to be examined
and tested by a competent gunsmith.
PISTOL DESCRIPTION AND TERMINOLOGY
The names of basic pistol parts used in this Instruction Manual are presented
in Fig. 1. Nomenclatures of all CZ 40 parts are presented in the section Illustration
and List of Parts.
The CZ 40 pistol is manufactured in a number of versions which differ from each
other by their surface treatment, grip panels type, and especially by trigger mechanism
operation. The characteristic features of the CZ 40 pistol are:
- large capacity double-column magazine
- classic design
- comfortable grip and balance in either hand
- good results at instinctive shooting (without aiming)
- low trigger pull weight
- high accuracy of fire
- high reliability, even with various types of cartridges
- the slide stays open after the last cartridge has been fired
- the sights are fitted with a three-dot illuminating system for better aiming in
poor visibility conditions. Optional tritium or micrometrical sights can be
fitted on request to the customer’s specifications.
- the pistol’s high level of safety against inadvertent discharge, is ensured by
the safety features described below:

Version Function Safety
Safety Stop on
the Hammer
Firing Pin
Safety
CZ 40 B SA/DA yes yes yes
CZ 40 DAO DAO no no yes
Comments:
SA (Single Action)
The trigger mechanism operates in a single action mode of fire. The hammer is
cocked manually and then after pressing the trigger the pistol is fired. The trigger travel
is short, and pull weight is low. After each discharge the hammer remains cocked.
DA (Double Action)
The trigger mechanism operates in a double action mode of fire. The hammer
is cocked, released and the pistol fired by one pull of the trigger. The trigger travel is
longer, and trigger pull weight is higher than at SA mode of fire.
DAO (Double Action Only)
The trigger mechanism only operates in a double action mode of fire. The
hammer returns to the down position after each shot, and for the subsequent
shots must be cocked again by pulling the trigger.
Safety Features
Trigger Guard
Prevents unintentional pressing of the trigger, for example when the pistol is
dropped.
Inertia Firing Pin
The design of the firing pin prevents the firing pin from protruding through the
face of the slide when the hammer is in its rest position. This eliminates the
possibility of a discharge when a loaded pistol is dropped on the hammer.
Firing Pin Safety
The firing pin safety keeps the firing pin blocked until the trigger is pulled. This
safety device minimizes the risk of accidental discharge through mishandling such
as when a loaded pistol is dropped.
Safety Stop on the Hammer
A half-cock safety notch is on the hammer so as to prevent it from striking the
firing pin when the hammer is manually cocked, and a thumb could slip. When
the hammer is on the safety stop, it is not leaning against the firing pin stop, but its
position is further back.

OPERATING INSTRUCTIONS
Ammunition
Use only factory-manufactured ammunition of appropriate caliber, which are in
compliance with CIP regulations (International Proof Commission for Firearms) or
SAAMI (Sporting Arms and Ammunition Manufacturers' Institute Inc. of the United
States). The use of other cartridges could damage the handgun or cause injury to
the shooter.
Note: The manufacturer does not recommend using any ammunition with
wadcutter types of bullets particularly LSWC (Lead Semi-Wadcutter). These types
of cartridges can cause a feeding failure when feeding the cartridge into the
chamber.
Removal of the Magazine
Hold the pistol in your right/left hand and depress the magazine catch with the
thumb/middle finger. The magazine will drop out freely (under its own weight) from
the magazine well.
Magazine Loading
With the open end uppermost, grasp the magazine in one hand. Place
a cartridge on the magazine follower. Press the cartridge down and back until it
touches the rear flat edge of the magazine. Place the next cartridge on top of the
previous cartridge and press down and back (Fig. 2). We recommend that when
some cartridges are already loaded in the magazine, depress them slightly with
the thumb of the hand which holds the magazine.
The number of cartridges can be checked through the inspection holes in the
sides of the magazine. Do not try to exceed the magazine capacity - doing so can
cause a feeding failure. Also, do not leave the magazine loaded for prolonged
periods whenever unnecessary.
Pistol Loading
CAUTION:
ALWAYS MAKE SURE THE PISTOL IS POINTED IN A SAFE DIRECTION WHEN LOADING!
Insert a loaded magazine and ensure that it has engaged the magazine catch.
Hold the pistol by the grip with one hand, and with the thumb and index finger
grasp the serrated finger grips on both sides of the slide. Retract the slide to the
stop and allow it to snap forward (Fig. 3). This procedure inserts a cartridge into
the chamber. The pistol is now ready to fire, all that remains is to squeeze the
trigger. If you are an owner of a pistol having SA/DA selective mode of fire and if
you do not intend to shoot immediately ensure the pistol safety by one of the
methods described further below in the section: Engaging the Safety Mode.
19
Page 7
CZ 40 - INSTRUCTION MANUAL
Reloading During Shooting
When the last cartridge has been fired the slide will stay to the rear. Remove
the emptied magazine and replace it with a loaded one. Thumb down the slide stop
with the shooting hand (Fig. 4), or with the other hand draw back the slide and
allow it to snap forward (Fig. 3). The pistol is again loaded and ready to fire.
Unloading the Pistol
ALWAYS MAKE SURE THE PISTOL IS POINTED IN A SAFE DIRECTION!
- remove the magazine
- draw back the slide and verify the last cartridge has been extracted from the
chamber and ejected
- let the slide snap fully forward
- depress the trigger (dry fire)
Engaging the Safety Mode
Push the safety up to the Safety-On position (Fig. 5) until the red warning dot is
covered. The safety in this position blocks the trigger mechanism and slide, thus
preventing the pulling of the trigger and operating the slide. The safety can be
engaged only when the hammer is cocked, and for this reason it is applied
especially in the case of a short-term interruption of shooting.
Besides the method previously described it is possible to put the pistol into
a safety mode and still be ready to fire immediately:
Load the pistol. Grasp the grip, POINT IN A SAFE DIRECTION. With thumb
and index finger of the other hand hold the hammer firmly (Fig. 6), pull the trigger
and release the hammer slowly and gradually until it rests on the firing pin stop.
Release the trigger. Apply extreme caution when lowering the hammer to avoid an
accidental discharge! We strongly recommend to practice this operation
beforehand with the pistol unloaded.
In this state the pistol is safe for all normal handling and at the same time ready for
immediate use. The design of this handgun incorporates the feature that the manual
safety can not be applied when the hammer is not cocked in order not to reduce
the readiness of the pistol for use by accidental engaging of the manual safety.
Please remember that the safest way to secure a pistol, is to unload it and
store it in a safe place!

CZ 40 - INSTRUCTION MANUAL
Sight Adjustment
The pistol sights were sighted in at the manufacturing plant at a distance of 25 m so
that the mean point of impact approximately conforms to the point of aim.
Windage correction can be carried out by drifting of the front sight in the
dovetail followed by the securing of its position by an indentation. Elevation
correction is carried out by exchanging the front sights for higher or lower sizes.
The usual rear sights may optionally be exchanged for a suitable adjustable sight,
or as the case may be, to install tritium sights. These adjustments should be
entrusted to a competent gunsmith.
MAINTENANCE INSTRUCTIONS
Stripping for Cleaning - Disassembly
POINT YOUR PISTOL IN A SAFE DIRECTION!
1. Remove the magazine. The pistol must not be disassembled with the magazine
inserted!
2. If the pistol is equipped with a manual safety shift it to the „Safety-Off“ position
in order that the slide can be manipulated.
3. MAKE SURE THAT THERE IS NO CARTRIDGE IN THE CHAMBER!
4. When disassembling pistol having SA/DA selective mode of fire rotate the
hammer backwards, until it is caught by the hammer main notch. All further
procedures will thus be performed more conveniently.
5. Put your left thumb through the trigger guard and with the other fingers grasp
the top of the front part of the slide firmly (Fig. 7). With the DAO version push
the slide slightly back until the two recesses on the rear part of the frame and
slide will be above each other. With SA/DA version the recess on the rear part
of the slide shall be above the red dot marking the safety engagement.
6. KEEPING THE RECESSES ABOVE EACH OTHER push the slide stop from
the right hand side of the firearm, using the magazine base corner protrusion
for example (Fig. 8). Remove the slide stop.
7. Pull the slide and the barrel forward off the frame.
8. Remove the recoil spring and guide and finally the barrel.
No further disassembly is needed for routine maintenance. When a great
number of cartridges has been fired, it is advisable to also disassemble the firing
pin and magazine.
Re-assembly Note:
Grasp the pistol in the manner described in point 5 and align the LINES on the
frame and slide, insert only about the half of the slide stop into the appropriate hole in
the frame (Fig. 9). Then shift the slide further to the rear, till the RECESSES are above
each other and in this position insert the slide stop completely into the frame.

CZ 40 - INSTRUCTION MANUAL
Firing Pin Disassembly
Firing pin disassembly procedure and cleaning should be entrusted to a competent gunsmith.
Magazine Disassembly
To remove the magazine base, push on the base lock which sticks out through
a hole in the base and slide the base about 5 mm towards the front of the
magazine. Cover the base with your thumb to prevent losing the magazine spring
and with the other hand take off the base from its guiding rails. Be careful during
the disassembly as the spring could fly out, or even cause an injury.
No further disassembly of your pistol is recommended. Should your pistol
require adjustment or repair be sure the task is entrusted to a competent gunsmith!
Note for the Service Technician:
Drift the extractor pin out from above, and drift it in from the inner side of the
slide; when the pin installment had been completed secure it with an indentation.
The rear sight, front sight and other solid pins and roll pins drift in from the left side
(when looking in the direction of fire).
Cleaning the Pistol
Clean the pistol
- each time you use it
- if you get your pistol wet
- as soon as possible after shooting
- at least once a year in a temperate climate
- as often as once a month in a tropical climate, or other demanding
environment
Cleaning the Barrel Bore and the Cartridge Chamber
If the pistol has not been fired or if only a few cartridges have been fired, clean the
barrel bore and cartridge chamber by the clean patch attached to the cleaning rod.
Repeat the cleaning, changing patches, until the last patch comes out clean.
When the barrel bore is very dirty, apply a gun cleaning solution using
a cleaning brush. Let the solvent act for about 10 minutes (this time may vary
depending on the solvent agent being used). Then thoroughly scrub out the barrel
bore. Subsequently, dry the barrel bore and cartridge chamber with a clean patch
and check that all powder residues or fouling have been removed. If necessary
repeat this procedure.
The cleaning rod and the brush must be inserted into the barrel bore from the
chamber, to prevent wear or damage to the muzzle. Pass the brush all the way
through the barrel bore before reversing the movement. If you try to change
directions with the brush in the barrel, the brush could stick.

CZ 40 - INSTRUCTION MANUAL
Cleaning of Other Pistol Parts
Other parts of the pistol (including the external surfaces of the barrel) should
be cleaned with a dry cloth, old toothbrush, brass bristle brush or a wooden
scraper. Preserving oil or paraffin oil can be used for proper cleaning. Never use
the agent designed for barrel bore cleaning! These solutions could remain in the
joints, and after some time could cause corrosion.
Check that cloth particles or brush bristles have not become lodged in any part
of the pistol.
Preserving
When the barrel bore, cartridge chamber, and all accessible parts are clean
and dry, wipe these parts with a cloth soaked in gun oil or apply the oil in a spray.
Remove all excess oil.
Before shooting always wipe the barrel bore dry. At very low temperatures
remove the oil from all accessible parts or apply a lubricant prepared especially for
these conditions.
Use thick preserving agents for example, preserving grease only for a long-term
storage in demanding climate environments, and before any use of the pistol it
must be thoroughly removed from all parts of the firearm.
