So I went and bought a new python as I remember shooting my father in laws years ago and it was great to shoot. I am noticing that the trigger is very heavy. Wouldn't break at 3.5 lbs. I am being told that for single action it is between 3.5 and 5lbs. I am going to get it tested as I think it is over 5lbs but even at 5lbs or even 4lbs, that is very heavy . Anyone ever experience the same on the old ones?
