    Pump Mag springs - Stainless or Carbon?

    In looking around for some more pump mag springs (my son is on his last one), I found the smalley part number again (C100-M1) but I noticed they come in stainless or carbon.

    Which one are you shooting?

    Given that the marker breach area is often wet, I would go with a stainless wave spring over a carbon steel wave spring to keep it from rusting.
    Except for the Automag in front, its usually the man behind the equipment that counts.

    I'm not 100% sure but I think stainless spring will tire sooner. Could the carbon option be actually spring steel(which would last longer)? Spring steel

    That was my initial thought. Smalley just says they are good for corrosion, and my assumption is that they simply cost more for a similar performance if all else is equal.

    Our carbon springs have been brittle, loosing a piece at a contact point after about 4-5 cases. I'm wondering if our bumper is too thin, causing too much compression, or if I have some "close to" smalley springs. I went ahead and asked for a sample from Smalley. I think I got my last batch from Rainman.

    The failure rate isn't so bad, it's just that the odds are that it happens while your playing and rarely in the staging area.

    Any good quality metal can be used for making springs. The "spring" is a result of quenching and tempering the metal. This hardens it and makes it remember its new spring shape. Obviously, a harder base metal will create a harder spring.

    Yeah, all things being equal though, common stainless alloys don't do so hot as springs, with poor heat treat and stiffness characteristics. Smalley does say they have a special process though. That's another reason that I'm wondering where my old springs came from.
