The trick is to make sure you have the right extension rings (people often miss removing the 7mm kick ring when they don't need it), and adjust the connector screw in the button assembly properly. Experiment with backing that screw out and tightening it in until you get the fit and action you like.
Once set, if it's clicky sounding, it might be that the contact's threads are fitting loose. Back the screw out, put a bit of dental floss vertically across the threads, and put the screw back in. That'll tighten it up a bit and might get rid of the click.
There are also magnet kits you can get. Just try Nemisis magnet kit in google to get all sorts of hits.
