I'm not trying to dispute or be skeptical about any ones reported trigger weight readings, but I think it's important to remember that the way that a trigger weight is checked is very important.
If the trigger is tested by quickly pulling back the trigger gauge, the resulting rating will always be much lower. The correct way is to pull the gauge back as slowly as possible, preferably with the gauge in the center of the trigger.
Again, I'm not disputing any ones readings, but I know from experience that the readings can vary by sometimes as much as 2 to 3 pounds just by how the test is taken and how fast/slow the gauge is pulled back. I can take one of my pistols and get wildly different ratings by doing either a fast pull, or a slow pull.
