Okay examined the decocking on my 36 and 638 the other night. Did about 30 repetitions with each. Mechanically they both decock fine. However with the shrouded hammer 638 is much easier to hang up the hammer part way and then force the firing pin to engage when you try to correct the error. Or at the range under a bit of stress trying to use fine motor skills to pull the trigger whole riding the hammer nub down.
