    For optimum function the mainspring and the recoil spring are a balancing act.

    A heavier mainspring would allow for a lighter recoil spring thereby reducing wear and tear when the slide moves forward. The thing is there is a point of diminishing return with this. At some point the recoil spring won't have enough oomph to push the slide forward fast enough to strip the next round and get it into the chamber.

    For fun you could experiment with various combinations of springs to find the lower limit of recoil spring weight that will still reliably run the gun. I'd be interested in what you come up with.

    i'm just looking into different things to try. probably going with 18lb recoil standard and 23 pound hammer spring. may work on the beavertail grip safety to a more comfortable feel then back to range. oh yeah when I find ammo. lol

    Ammo shortage? Just do what I do. Take up a rock solid stance, get a perfect sight picture, and then say "bang". I never run out of ammo and I always hit the bullseye. I guess I'll have to keep doing this until the shelves get restocked.

    Just a suggestion but I would highly recommend a 14lb or 16lb recoil spring unless you're going to feed your blaster a steady diet of +P ammo.

    No advantage in a 25 pound mainspring.

    affects of heavier mainspring

    i am hoping to draw joe chambers into this discussion of various power mainsprings.

    I understand what one might accomplish by installing mainsprings of 23 pounds and heavier and then balancing the recoil spring.

    have any of you noticed any affect on accuracy, as tested via ransom rest, with installation of heavier mainsprings, such as 23 or 26 pounds?

    just wondering.

    Just so we're all on the same page. The Colt factory standard for 5 inch barrel 1911's in .45ACP is a 23 pound mainspring and a 16 pound recoil spring.

    After playing around with several different spring weight combinations (including use of the 25 lb mainspring) I have found the "stock" configuration of a 16 lb recoil with 23 lb mainspring to be the most reliable setup.
