That would be because trigger trapping IS a shooter error. I can attest to the Citori and Beretta triggers being mechanically different, but they are about equally poor in regards to factory stock "feel".
Seems to me that defective wiring would have little relationship to some mechanical aspect. Might be interesting to take a poll somewhere and see if brain farts cluster around a brand name.
