I picked up a Janty case from Janty that came with two of their button cover/protectors. Then I picked up some of the cover/protectors from Cignot. I use them to keep the button safe from accidental firings while in either of my cases. They are easy to use and very convenient. The Janty ones are nicer than the joye ones IMO as the janty covers internally surround the button and won't rotate where the Joye ones will to a degree. Unfortunately, the Janty ones are only available with the case at this time, so it's not really a cheap method. The cignot ones are 2 for a buck if i recall. Either will get the job done.
