22. Never alter any parts of your pistol as the safety and proper function of your pistol
could be seriously compromised.
23. 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.
RULES OF THE SAFE HANDLING TRITIUM SIGHTS
The tritium sights MEPROLIGHT type ML-17777 for CZ pistols involve a luminous front
sight (tritium radiator of 0,565 GBq activity) and a luminous rear sight (2 tritium radiators of
0,444 GBq activity) that is installed at 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 manipulation and storage of the sights is not exposed to any risks.
The third generation of the sights retains all the advantageous features of the preceding
generation of MEPROLIGHT sights and several improvements are added:
- built-in shock absorber
- solid protective bushing providing less sensitivity against rough manipulation
- immovable crystal window for a 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 Israel armed forces)
protects the sights against an accidental damage, avoids the unwanted
manipulation with the light source, inhibits to penetrate the dirt into the visual
system and to hide the light
- provided a finer transition between the aiming during the day and the night
- simple installation (no modification of the arm is necessary)
- no added weight nor size
- no maintenance
- no battery needed (no losses of the energy at the cold weather)
Safety instructions in case of the sights damage
In regular conditions of the storage, use and maintenance there is no risk to the user
caused by emitted ionizing radiation, because it doesn't penetrate metallic caps, in which the
ampoules with radiators are fixed. In case of a nearly unreal incidental damage of all
ampoules in one set at the moment, when the arm is in shooting position (position of the
sights closer 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:
