Welcome. Your English is fine, don't be concerned.
I bought a Kadet kit to put on my cZ75. It was easy to fit and have shot over 1000 rounds with no problems. It has become one of my favourites and I seldom go to the range without taking it along.
Do you have a cZ75? If so, can you buy the kit? I am sure you will not be disappointed with a Kadet.
