�Does anyone know heights/lengths at 1911 springs are rated?

I have several Recoil Guide, Hammer and Firing Pin Springs and I would like to measure their capacity properly.

For example �Which is the height/length all Recoil Guide Springs are when they support their specified loads? This lenght must be the same for all Recoil Springs 12 14, 16,18,20 lbs. Probably this length is, or depend on, a pistol dimension which is shown in 1911 Blueprints or Manuals, I do not have one .

I will thank all information about respective Rating Heights/Lengths for three above mentioned Springs.

I measure spring force in the pistol with weights pulling down on the trigger gaurd while I hang on to the slide.
The weight that just makes the slide go all the way back to the stop is the measurement I write down.
I once made a triple recoil spring assembly from the Wolff gunsmith pak. It is 14 pounds to open the action and 42 pounds when the slide reaches the stop. I call that a 42 pound recoil assembly.

Thanks Clark.
I will try your method writing down values for all Recoil Springs I have.
