do you test or just replace recoil springs after "X" amount of rounds? but what about if it's failing on rated pressure by 1 or 2 #'s that make or can make the difference! do you test or have a way to test spring with it assembled? well i do after getting to know how springs are rated as in are they listed as pressure when at ejection length or at battery lengths. from my finding the springs are or can be tested for pressures at 1" from/out of battery. place gun in a sturdy manner, place gauge behind grip and pull forward for readings. most guns will have a less than 18# spring as most are 14-16# factory rated. although this gauge only goes to 8# i do have a digital that goes higher.
