							CZ 100  -  INSTRUCTION MANUAL 14 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 barrel bore, chamber, and action are clean 
and clear of obstructions. After shooting, clean a 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. If possible wear both 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 a damage you 
may not see. If something like this happens allow the pistol to be examined 
and tested by a competent gunsmith.  
						

							CZ 100  -  INSTRUCTION MANUAL 15 PISTOL DESCRIPTION AND TERMINOLOGY 
 
The names of basic pistol parts used in this Instruction Manual are presented 
in Fig. 1. Nomenclatures of all CZ 100 parts are presented in the section 
Illustration and List of Parts. 
 
The CZ 100 pistol is a semi-automatic handgun with locked breech. It is 
produced in several versions. Characteristic features of all versions are: 
 
- ergonomical shape allowing shooting to be carried out by left or right hand 
- comfortable grip and balance 
- good results at instinctive shooting (without aiming) 
- high accuracy of fire 
- long service life 
- high reliability, even with various types of bullets 
- the slide stays open after the last cartridge has been fired 
- illuminated sights for aiming under poor visibility conditions 
- The pistol incorporates a DAO firing mechanism. After each shot the firing 
pin returns to its rest position and is blocked there. The firing mechanism is 
uncocked, and the pistol is safe even when dropped 
- The absence of an external manual safety contributes to an immediate 
readiness to fire, and thus ensuring a heightened rapidity of response for 
the decisive first shot 
- The wide trigger guard prevents snagging of the trigger by any objects, and 
also any unintentional discharge during handling or dropping of the pistol 
- The slide can be cocked even with only one hand by positioning the rear 
sight or slide protrusion against any fixed edged object and levering 
against that point 
- The CZ 100 cal. 40 S&W is provided with compensator ports to reduce 
muzzle climb during firing 
 
Comments: 
DAO (Double Action Only) 
The trigger mechanism only operates in a double action mode. The firing pin 
returns to its rest position after each shot, and for the subsequent shots must be 
re-cocked by pulling the trigger. This guarantees the same conditions (trigger pull 
and travel) for every shot. 
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.  
						

							CZ 100  -  INSTRUCTION MANUAL 16 OPERATING INSTRUCTIONS 
 
WARNING: 
Before shooting always wipe the barrel bore dry, and lubricate the slide guiding 
rails with a suitable lubricating agent. 
 
Ammunition 
Use only factory-manufactured standard 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 malfunctions or injury to the shooter. 
 
Removal of the Magazine 
Hold the pistol in your right/left hand and depress the magazine catch with the 
thumb/middle finger and by the other hand remove the magazine. 
 
Magazine Loading 
With the open end uppermost, grasp the magazine in one hand. Place 
a cartridge on the magazine follower (Fig. 2). 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. 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. 
 
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 and the pistol is now ready to fire. In the case of any emergency the 
pistol can be loaded even with only one hand, by the use of the barrel stop placed 
against any fixed edged object.  
						

							CZ 100  -  INSTRUCTION MANUAL 17 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) 
 
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 the drifting of the rear sight in the 
dovetail. Elevation correction is carried out by exchanging the rear sights for 
higher or lower sizes. 
 
Loaded Chamber Indicator 
The loaded chamber indicator protrudes from the side wall surface of the slide, 
thereby indicating the presence of a cartridge in the cartridge chamber. The loaded 
chamber indicator status can be checked both by sight and by touch. 
 
CAUTION: 
In consideration of the fact that the firing pin block is located under the rear 
sight, do not drift out the rear sight completely from its dovetail. Entrust 
eventual rear sight exchange to a competent gunsmith.  
						

							CZ 100  -  INSTRUCTION MANUAL 18 MAINTENANCE INSTRUCTIONS 
Stripping for Cleaning - Disassembly 
ALWAYS MAKE SURE THE PISTOL IS POINTED IN A SAFE DIRECTION! 
1. For the safety reasons remove the magazine first. 
2. MAKE SURE THAT THERE IS NO CARTRIDGE IN THE CHAMBER! 
3. 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. 5). Push the slide slightly back 
until the position of the recess in the slide enables the removal of the 
connecting pin from the pistol frame. Press down the connecting pin from the 
right hand side of the firearm as deeply as possible (the magazine floorplate 
corner can be used to facilitate this operation) (Fig. 6). Pull out the connecting 
pin from the left-hand side of the pistol frame. After removing the connecting pin, 
ease the slide back to its initial position driven by the force of the recoil spring. 
4. Grasp with one hand the pistol grip (as when shooting - see Fig. 7) and with 
other hand retract the slide back approx. 5-10 mm to get the trigger 
mechanism out of engagement. Pull the trigger and slip the slide barrel 
assembly forward off the frame. 
5. Ease the trigger pull. 
6. 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 clean the firing pin and magazine. 
 
Firing Pin Disassembly 
Using a suitable tool push in the rear end of the firing pin main spring guide 
(below the level of firing pin retainer), and shift the firing pin retainer approx. 2 mm 
down (Fig. 8). Then cover the firing pin retainer with your thumb (in order not to 
lose the spring-loaded guide with its spring), and with the other hand pull the firing 
pin retainer completely off the slide. Be very careful at this stage of the 
disassembly procedure, as the spring with its guide are spring loaded and could fly 
out, thus getting lost, or even causing injury. By means of a suitable tool depress 
the firing pin block, and withdraw the firing pin with the firing pin insert, main 
spring, arid firing pin guide from the slide. 
 
Magazine Disassembly 
The magazine base is removed by pushing on the base lock, which stick out 
through a hole in the base. Slide the base about 5 mm towards the front of the 
magazine (Fig. 9). Cover the base with a thumb to prevent the loss of the magazine 
spring. At the same time, disengage the base from its guiding projections with the other 
hand. Be careful at the disassembly as the spring could fly out even cause an injury. 
WARNING: 
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!  
						

							CZ 100  -  INSTRUCTION MANUAL 19 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. 
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. 
 
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 metal 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. The plastic parts do not need any preserver application. 
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.
