Wolff Buffer Springs: Composition/Lifespan?

Does anyone know what the composition/lifespan is of Wolff buffer springs? Thx…

It’s rocket wire (proprietary formula). I use them in my handguns to great effect. For what it’s worth, they last a shitload longer than Glock factory springs for both the recoil spring assembly, magazine springs, and the striker spring.

Any idea how service life compares to CS springs? Thx!..

Nope. Sorry brother.
