If you're it's that new mod.........the one with a ram of it I forgot the name.it has a lil ball bearing in the switch of it.grim green did a review of it.they sent him a new switch,it's packed in some kinda no smell,no taste kinda grease or something.did say anything about auto firing.
Yes grease is going to help (electrostatic grease) however it's not a physical barrier or failsafe. Might sound finicky but the grease can fade or get washed out or in the event that the ball pushes through the grease. Yes it might help but it's not what I would call a proper solution and rather a band-aid. Feel free to disagree, once I figured it out I posted. The rattle was when they shook it up and down, none of the reviews I've seen have actually shown this happening and I don't know if anyone would have thought about it. So hence why I felt like I had to say it (especially since I have praised it).
