很多人问这次团购的CZ75 SP01的氚气灯夜瞄是不是cz custom自己装的，答案是：不是。说明书附上，shadow本身在工厂可以选配三种瞄，普通，光纤，氚气。看经销商怎么订货了。
说明书里写着：“The sights comprise of a fiber optic front sight and tactical rear sight, on special
request tritium or micrometrical sights can be installed”（Pistol description and terminology).
经销商订光纤的多，因为白天打比赛打铁耙有优势。不过氚气夜间绝对好用。这次赶上CZ custom定了一批氚气的，没赶上的得自己换了。
说明书我转换成图片了，注意看第4页（从封面开始数）的重要信息：Rules of the safe handling tritium sights
RULES OF THE SAFE HANDLING TRITIUM SIGHTS
The tritium sights MEPROLIGHT type ML-17777 for CZ pistols involve a luminous front
sight (tritium light source of 0,565 GBq activity) and a luminous rear sight (2 tritium light
sources of 0,444 GBq activity) that are installed on the pistol by means of precision
dovetails. Tritium in the gaseous state (99% HT and 1% HTO) is enclosed in borosilicate
glass ampoules with a luminescent element and these ampoules are fixed by glue into the
metallic cap of the sight so that the handling and storage of the sights are not exposed to
any risks.
The third generation of sights retains all the advantageous features of the preceding
generation of MEPROLIGHT sights and several improvements are added:
- built-in shock absorber
- solid protective housing providing less sensitivity against rough manipulation
- immovable crystal window for better light output with additional protection against
a damage
- tolerance against longer immersion in currently used solvents and cleaning agents
- guaranteed continuous available light intensity for the period of 12 years
- MV sealing design (the only design tested and approved by Israeli armed forces)
protects the sights against an accidental damage, avoids the unwanted handling
of the light source, inhibits the penetration of dirt into the visual system and to hide
the light
- provides a finer transition for aiming during the day and the night
- simple installation (no modification of the arm is necessary)
- no added weight or size
- no maintenance
- no battery needed (no losses of the energy in cold weather)

Safety instructions in case of the sights damage
In regular conditions of storage, use and maintenance there is no risk to the user
caused by emitted ionizing radiation, because it doesn't penetrate the metallic caps, in which
the ampoules with the light sources are fixed. In case of the hypothetical accidental damage
of all the ampoules at the same time, when the arm is in the shooting position (position of
the sights closest to the shooter), the single effective radiation dose wouldn't exceed the
value of 0,26 mSv. What does this value present? It is for example:
- 1/12 of the dose which is received by an ordinary inhabitant in course of a year
due to natural background radiation (3,5 mSv / year)
- less than 1/4 of the general effective dose limit to an ordinary inhabitant
Recommended first aid at the inspiration of the gaseous tritium
The gaseous tritium state is practically inactive and causes a slight internal
contamination. In case of its ingestion it is recommended to increase the intake of liquids and
eventually to take some diuretic for acceleration of body water exchange.
RESPONSIBLITIES OF THE TRITIUM SIGHTS OWNER
1. The sights are a radioactive light source for the period of 6,5 years after their purchase
according to Czech Republic legislation.
2. At purchase the owner receives a guide with the rules for the safe handling and a
document on the on the impermeability of the radioactive light source in the set
(certificate for the encased radioactive light source), which must be saved and
presented on the request of the appropriate authority.
3. When handling a type approved product, which is a source of ionizing radiation, it is
necessary to respect national regulations for protection against the ionizing radiation
(the appropriate national legislation).
4. In case of ownership of more than 9 sets of Tritium sights (the total activity exceeding
10 GBq) the owner is obliged to consult the requirements needed from the appropriate
national legislation and authority.
5. To avoid such rough handling, when damage of the sights may happen.
6. It is not allowed to carry out any changes, relating to the properties of protection
against the radiation.
7. In the case of destruction or damage, the sights must not be further used. The owner
is obliged to safely secure the device that is changed in a safe way and to pass it to
the distributor or the manufacturer for the safe disposal. The same procedure to be
applied for the disposal of used sights.
8. The handling of sights is governed by the general principles of the protection against
the ionizing radiation. At the current use there are no requested tests of to check the
impermeability during the service life of the sights.

The sights were type approved by the decision of the competent authority Ref. No.
25169/2005, index A1.
