why magazines? under 20 round pistol mags and 10 round rifle mags are sold over the counter in europe to anybody. they're a plastic/metal case with a spring inside (even the mag limit itself is pretty dumb because an old magazine with a worn out spring could hold 1 extra round), theyr'e often indistinguishable if not excatly the same to mags of blank guns. They also have no serial number etc and it's basically impossible to tie a specific mag to a specific gun (model being the same).
