No, instead replace them when their cocked force is 5% below spec.So, if I don't shoot at 1,000 yards, I never need to replace springs???
Compress it on a bathroom weight scale.How do you check the springs?
Firing pin spring. Yep, same.Springs take an initial set. After that, they have to be bent past their elastic limit to set any further. I have been working on guns for 50 years, and I have never replaced a spring unless it was rusted or overheated.
Good idea.I have a number of Army shop manuals from the 70s. None of them use spring weight (strength) as the serviceability standard.
Spring length is the standard.
