I have notice this also with my 442.
Totally pull this out of my arse but I believe that when you anodize scandium aluminum (the frame alloy) that you can get some scandium aluminum nitride formed in with the regular oxide process. Scandium aluminum nitride is a form of piezoelectirc material that then under high strain rates (ie snapping the hammer) could cause a voltage discharge. The same principle used in the click igniter of some lighters and gas grills. I could be total wrong on that too. |

They do that. They're known for doing that. Don't know why.
