You did not say what spring you are referring to.
The firing pin spring and trigger spring on a OEM Glock is 5.5#.
Most aftermarket trigger springs are 6.0#
The aftermarket FPS are 4.0#, 4.5#, 5.0#, 5.5#, 6.0#.

For a range gun using quality ammunition:
You can run a 4.5# FPS with OEM FP and OEM trigger spring and maintain reliability.
With a LW FP you can run a 4.0# FPS and OEM trigger spring and maintain reliability.
If it is a Gen 4 Glock and you use a 6.0# trigger spring you will Possibly have trigger reset issues.

Any of the lightweight firing pins will normally be reliable with a 4.0# spring if you are shooting Quality American made ammunition. Order a 4.0# and a 4.5# Wolff spring and if you get light strikes with the 4.0# install the 4.5#.
If you are shooting Garbage Ammunition things could be different.

If you want to know the energy in a specific spring, test it. You can also test a group of springs from a particular manufacturer for comparison to others. My experience with Zev #4 springs is that they are on the heavy side. LWD 4 pounders are the lightest I have found, out of the bag.

The OEM firing pin is fine with a #4 spring as long as you stick with Federal primers. The FP springs in my 34s measure in the #3.8 range and are 100% reliable with OEM firing pins.

Lightened FP's are more prone to breakage than the OEM part. Substantial trigger improvements can be made by honing and polishing the FP. It takes time to get an FP done right, and to get it fit properly. Once I've invested that time, I want the FP to have a long lifespan.
