I’m from France. Getting a rifle is pretty easy, you “just” have to get a psych evaluation and a shooting club registration / hunting license. But that gets you long, manual weapons with small magazines. You can keep the gun if your license expires.
Then you can get a stronger license if your shooting club vets for you. This allows you to get handguns and semi auto rifles.
Any auto gun or explosive is basically only authorized for use for the military.
Oh and anything that can be used as a weapon is prohibited from being carried around in public spaces (yes, it is that vague), and protective equipment is subject to authorization as well (gas masks, bulletproof vests etc)
You can read more on Wikipedia https://en.m.wikipedia.org/wiki/Firearms_regulation_in_France
Edit: Wikipedia does not seem to explain it, but A class weapons are basically military only. B class is what you get through shooting club vetting. C class is for anyone registered by a club / hunting license. D is adults only, with exceptions for criminals etc
