Washington State Police NCD's
The issues dogging Sig with their 'non commanded discharges' involving the 320 pistol seem to continue, and had me wondering:
With the spring tensioned cruciform/striker, or sear/striker (the terminology will differ) interface on a striker-fired pistol, would it be possible for vibration over days/weeks to INCREMENTALLY reduce engagement?
In other words, could the unavoidable vibration and minor impacts of a gun, especially one carried in a duty holster slowly, over time, reduce the engagement of the sear/cruciform/whatever with the striker, eventually cumulatively leading to a 'non-commanded discharge'?
As a corollary, does anyone regularly reload their pistol to ensure its striker engagement is reset to its fully engaged state?
I know there's been significant drop and impact testing, especially on Sig's 320, but has any ever checked for this incremental disengagement via vibration?
Note I'm not saying this IS happening; just curious if it's ever been considered.
