As I recall, France tightened their laws on semiautomatic firearms after the big Islamic terror incidents in 2015. I don't know the exact details of the current laws though.

I did a little research and it looks like it's possible to own semiautomatic firearms if you have the right permits, but it's not clear how easy it is to get those permits. If you're an IPSC shooter and belong to a club and compete, I think you can own the appropriate pistols, but it's probably more difficult to get an AR-15 or AK-47. I don't think the average person can just walk into a gun store and purchase a Glock.
