IIRC I heard chrome silicon holds up better?

Yes it does, and considerably so.

You heard correctly, they hold up much better than stainless steel

To corrosion?  No, not as well.

While a good CS spring can potentially last more cycles than stainless steel, a good stainless spring will last sufficiently long enough.  For example, we use a USGI-spec stainless spring in our PMAGs and they will typically last many thousands of rounds.

So what is the military using today? I'm ordering GI mags and I have my choice.

Milspec is SS.

CS lasts longer in terms of number of times you can compress/release before failure, at the cost being less corrosion resistant. I buy whatever is available at a good price and dont worry about it. Far more important that you get good mags than worry about the spring material.

Hi,

Each spring has its good and bad points, just a tip SS is just corrosion resistant, not rust proof.  I have CS springs in magazines still working dating back 40 some years.  I've also had SS springs fail in testing in as little as 30 cycles in shooting tests.  CS retains its strength much longer.
