I am not a gunwriter, however I use a Wheeler Trigger Pull Scale that has been compared to calibration weights in an instrument lab for an ISO 9001 certified company. The lab checks measurement tools to traceable measurement standards.

I also have a digital luggage scale that has been compared to similar calibration weights. I use it to measure overall rifle weight, and pull weights for my archery equipment.

In 20+ years as a research and test engineer, I've never seen simple instruments be so accurate and low cost until the past few years. Prior to that, most low cost spring scales needed to be calibrated before and after the measurement.
