							CZ 40  -  INSTRUCTION MANUAL 16 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 anyones 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.  
						

							CZ 40  -  INSTRUCTION MANUAL 17 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: 
  
						

							CZ 40  -  INSTRUCTION MANUAL 18  
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.  
						

							CZ 40  -  INSTRUCTION MANUAL 19 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.  
						

							CZ 40  -  INSTRUCTION MANUAL 20 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 21 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 22 Firing Pin Disassembly 
Firing pin disassembly procedure and cleaning should be entrusted to a com-
petent 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 23 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.
