UPDATE
Yesterday, Ministry of Interior introduced a draft of Governmental Executive Order that is supposed to implement part of the EU Gun Ban dealing with firearm conversions.
Firearm conversions were a popular way mainly for people who are into reenactment to have a real firearm coverted into firing blanks only. Other applications include conversions to fire pepper spray or flobert cartridges or deactivation - none of these require gun license or any additional permits as of now.
Sadly Slovakia had extremely poor conversion/deactivation standards and their "deactivated" firearms became one of main sources of illegal guns used by criminals in Europe. This was used as scapegoat by the European Commission to justify the EU Gun Ban after a number of terror attacks committed mostly with illegal firearms smuggled in from Balcans, but in case of Hypercacher Paris attack reactivated guns from Slovakia were used.
It seems that the Minister of Interior wants to be able to present some kind of development to the EU Commission now that the implementation process in the parliament has hit a stone wall.
The proposed Executive Order would mean that deactivated / converted firearms would be still considered as firearms, i.e. their owner would need firearms license - in case of firearms newly entered into market.
This would mean higher requirements for people who want to enter reenactment, possibly discouraging many in future from joining.
On the other hand many who simply "want to play" would probably get gun licenses... and once they have a license why not buy a real deal firearm instead of only a punny blank firing conversion?
Hence, paradoxically, this might actually lead to significant rise in firearm ownership over the next few years as reenactors will be forced to get licenses.
Which is something we are already seeing now with many new people getting licenses simply because they have a feeling this might be their last chance (mainstream media have been painting EU Gun Ban as a doomsday for civilian gun ownership which forced many to get licenses).
