Do Luger Parts Wear Out And Need Replaceing

Karl · 10-28-2014, 07:22 PM

I used to always replace the mainspring in a new (to me) Luger because it is a cheap part and I reasoned that there was no harm in replacing the spring but potential harm in shooting with a weak spring. However, now that I reload and have more experience with lugers I have learned that the old springs, despite the age, are usually just fine. Coil springs seem to keep their vigor better than leaf springs. Can anyone here with real engineering knowledge support this opinion?
