1911 spring longevity

[Skylerbone]

From the original post:

What about all the other springs in 1911 pîstols ?
(main hammerspring, firing pin spring, trigger/sear/grip safety spring..... even magazine spring)

This became a recoil spring debate at the insistence of respondents, not by the question asked. To that end, what depth of firing pin primer strike warrants a firing pin spring replacement according to those not buying the "snake oil"? How does one suspect the mag. catch spring is getting a little long in the tooth? At failure?

I have eight M1911 magazines

and they still function like new. Chip McCormick mags.

I replaced one at around 5,000 rounds, because it started to bounce brass off my head.

I'll keep mine until the end

My M1911A1 Springfield Armory .45s will go to the NRA when I die, along with four other handguns.
