Magazine Spring Failure

New Jovian Thunderbolt has written a post discussing magazine spring failure

I think the “spring tension is shot” excuse is a catch-all reason that is over used when us amateur gunsmiths run out of ideas. Like the way they blame ball bearings for everything wrong in turbofan aviation maintenance.

Here is an example of a spring ‘problem’ that wasn’t from the Cooper Commentaries:

“Our distinguished family member J.P. Denis of Belgium reports that he discovered an abandoned MP40, together with several magazines, in a building that was being torn down. This piece had been left unattended for 50 years with all magazines in full compression, and they all worked perfectly. I think this is marvelous. When you think of the degree to which our culture depends upon springs, it is good to know that spring construction is so well understood.”

An interesting post. We really do rely on our magazine springs. Read it here.

    I was once told by an engineer that if properly manufactured for the intended application, a spring should never wear out, no matter how much use it sees (within specification).

    Wikipedia seems to agree with this.

    But most gunsmiths I´ve talked to or read about seem to recommend exchanging springs routinely nonetheless.

    The only reason gunsmiths say to replace your springs every so often is so the can make money I have an M&P 9MM that came with three clips and I have gone through well over 15000 rounds in the three clips over the last couple years and as long as you clean them every now and then you should have no problems I haven't.
