I have kind of an oddball question. Recently I picked up an S&W 442 to serve as a carry piece for running, and as a maximum concealable gun for non-permissive situations. It's been pretty great for both, but there's one annoyance: There's enough headspace at the back of the cylinder that, especially when running, I can hear the cartridges clicking up and down. This might be endemic to revolvers, but has anyone ever rigged up a fix to cut down on the rattle? I dunno if J-frames can accept a super skinny moon clip, or if I could just tack a little piece of masking tape to the back of the casing, or what. Any ideas?
