Any record, pins door retention, have never been implemented because they do not fit as they are placed; the locking plate on one side, was too broad of 2-3 millimeters, I adjusted with sheet metal shears; implementation difficult trap for triggering the stem is put next to the slot provided for this purpose, otherwise impossible to arm; arming on site, do not shake !! .. I would say: could do better, everyone has no shear plates and patience I have shown
