I don’t have any problem with Ruger BX mags. Maybe it’s an ammo issue? In any event, they are irreplaceable under this state’s current laws, so it behooves you to figure out why they aren’t feeding properly and fix them.
I’d start with cleaning them, maybe deburring if needed. Lube with a quality dry lube. Use quality ammo. They will work, you just need to find out why they aren’t feeding. If all else fails, disassemble them and see what's going on inside.
