Read this over on 1911forum and thought I would pass it along. I tried it myself yesterday.

Last night I took my two mag springs from my SW40E and measured them at 6" total length. I stretched them to 7.25", pulling from the ends. Then I put them in my oven at 350F for 35 minutes. When done, I removed them and put them on a ceramic plate to cool to room temp. Reinserted into the mags and they're a lot stiffer...

Don't know the dynamics, but will let you know how they hold up.

Just stretching them to 7.25" should make them stiffer. 350 degrees shouldn't affect the metallurgy, SFAIK. Whatever effect there would be would be to soften the metal, annealing, but you'd have to get up toward a dull red--900? 1,100?. If annealed, the springs would no longer be springs; they'd be malleable wire.

To harden a wire, heat it to the dull red and quench it in oil at 350 to 400 degrees...

That's why I'm asking the question. I wasn't sure how this worked. Maybe it was a BS post...
