That's a cool idea. I think I have some snap caps somewhere, but I havn't got out my reloading stuff yet. That piece of yellow plastic that you see in the picture behind the cylinder I assume does the samething as well as letting you know it isn't loaded. I am a believer in dry firing some types of guns and not others. I've never broken or damaged any of them from doing it and I have one rifle that I've had for 41 years and is still fine. I think it falls into that Chevy and Ford arguement. No winner. LOL
