That is unfortunately not true. According to the latest info from Dita Charanzova, which is basicaly the only relevant MEP in the whole EU parlament who fights against the crazy gun ban law, Commision just reached agreement with EPP and SD (who hold comfy majority in EP). They agreed on ridiculous things such as selling semi-automatic weapons will be completely banned, while those who already own them can keep them (because it would be too expensive to confiscate them by EU), ban on magazines with more than 10 rounds, limited gun license by 5 years, mandatory psychical test, and this is just a tip of an iceberg. The details are not known yet, but if Commision agreed on a “compromise”, it means that 90% of their madness stayed in the law, because they were absolutely uncompromising, while MEPs were really lax and they were easily making one concession after another the whole time. Needless to say that even if “just” 50% of what they proposed stayed, it would be still terrible and totaly devastating to the czech gun laws, because 50% of insane law is still 50% insanity.
edit: And I also wouldn’t be so sure about implementation of the law by czech MPs. The only party that is principaly against more gun restrictions is ODS, which is dead party. TOP09 are neomarxists who will vote for the restrictions in an instant once it is ordered by EU, no matter what they say now (at least half of their MEPs will support it already in EP, mark my words). CSSD is split into two groups, while the one currently in command (people around Sobotka) are neomarxists who support gun restrictions. ANO has no principal stance on anything, they are currently against the gun ban, but once EU threaten to halt subsidies, they will all support it without blink of an eye. And counting on communists is also not very wise, considering their general support for state control of everything.
