    I would really like the answer to this question:
    It is a fact that properly made springs don't get weak-if anything, they get harder and break. If a spring is worked past it's elastic limit, the spring can fail, but usually they break in this instance, too.
    Now, let me quantify my statements-I make a lot of springs. A metallurgist I am not, but nevertheless-I make a lot of springs. The 1911 recoil spring can only be compressed so far, and I don't believe the 1911 design over-compresses it. The only way to "weaken" a spring except overcompression/extension is to overheat it. I doubt this is the case. Machinegun springs don't readily wear out, that I am aware of.
    Perhaps modern 1911 springs are made of stock that is too thick-allowing it to bind and batter the frame?
    Looking for intelligent answers....

    Bill, I'm afraid I can't give you the answer you are looking for. Only my experiences working on and shooting these guns for 50 years. These springs do wear out as in getting weak. So to avoid reliability issues and correct problems, we change springs. I hope this makes sense. :)

    No. The Commander uses a 20 lb spring.

    It's a misprint. Use the 20 lb spring in a Commander.
