    I want to get a Taurus Millennium Pro in 45 caliber but I am concerned about something. For home defense it will be loaded at all times and that gives me two options in order to bring the pistol into action;
    1. I would have to actuate the slide to chamber a round (in the case of a home invasion in the dead of night chambering a round will cause a lot of noise and give away my position or it could cause an assailant to open fire immediately) or
    2. I would need to already have it cocked, which brings me to my question, since the firing pin spring will be under constant pressure (for years) will the spring eventually lose it’s energy causing the pistol not to fire?

    Thanks in advance for your input :)

    no, long as it is not allowed to rust in place for lack of attention it will be fine for decades of light to medium use. springs are not damaged by leaving them under compression for years.

    Something like this for home defense would eliminate problems #1 & #2.

    You should also not be leaving the Spring compressed for years at a time. Shooting tends to be a perishable skill, and if somebody breaks into your home, your life very well may depend on not screwing up. Practice until you can't get it wrong.

    Magazine spring madness: 'creep' to your 'elastic limit' to un-earth the urban legend of 'spring-set' | American Handgunner | Find Articles at BNET

    "To put this one to rest, you have to understand creep. Creep is the slow flow of a non-ferric metal like copper, brass and lead under force. At temperatures outside of a furnace, steel doesn't have any appreciable creep. Under most conditions, steel flexes and then returns to its original shape. When pushed past its elastic limit, steel will bend and not return to its original shape. All designers of well-made magazines make sure the spring never approaches the elastic limit when the magazine is fully loaded. Honest. This means the spring will not weaken when the magazine is fully loaded -- not even over an extended time. Like 50 years. American Handgunner recently ran a story about a magazine full of .45 ACP that had been sitting since WWII and it ran just fine on the first try. So there you go."
