    I have owned a PM-9, a P-45, and currently have a K-9. I have always kept each of them loaded, almost continuously, even when storing them in a safe. They have good springs, and a good spring only fatigues from much repeated use - not from being stored in a compressed state.

    And yes, they work similar to a Glock.

    Springs fatigue from repeated compression and decompression, not from being left in a static state. You should be fine.

    Is it better to leave it loaded indefinatly then to unload it every week or two and let it rest for a day? I unload it because what I have read about not leaving the magazine spring compressed all the time.

    Yes.

    Springs wear out from the act of compression and decompression together. Compression alone will not wear out the spring.

    Maybe a tiny amount, but nothing worth worrying about. The above is true for springs in general.
