Ian McCollum did it in his video about the sig issue. Basically, the p320 hammer is always under full tension. This means that if the gun has any other problem that makes the hammer drop, it will always cause an uncommanded discharge. Glocks don't have this problem because their internal hammer is under half tension; the user brings it up to full tension with a trigger pull. Sig made the p320 have a full tension hammer all the time because it made the trigger nicer.
