Don't apologise for your English as it is far better than most peoples Portuguese. Interesting to learn that the cZ 100 and 110 are discontinued. Purchasing a discontinued model always raises a question. I have a number of cZs and have never had a problem with any of them. However, I do not have a 100. The 110 was never available over here. Yoiu could always purchase some spare parts and keep them in the event of a problem sometime in the future. More than that, I would question purchasing a 100 or 110 in any case. I have read the triggers on the 100 and 110 are very long and gritty and this reason has kept several freinds from purchasing them. I am only speaking from what I have heard and read and have not had the opportunity shoot one. Good luck.
