Russia doesn't have any way to match sanctions "blow for blow".
But the more effective sanctions also have an impact the other way to implement such as cutting off gas and there is going to be a lot of impact from separating entangled interests with some people and companies much more hit by it than others, etc. Russian money and interests are everywhere.
To keep the pressure up on Russia is going to mean much more widespread sanctions, etc. ongoing and some of that is going to be felt the other way - and we need to be smart about that.
