In order to pass the CRT/MRT test you must use a staple gun to attach a replacement grip to the handle.
Personally I don't use a staple. The double sided tape on the girp works fine, if make sure the pallet is clean before starting. If a staple had to be used, I would re-use the original staple and use the same holes it was pulled from. It can easily be held with needle nose pliers and tacked back in with a tack hammer.
