What did it say on your order?? If it's not there call Wolff and ask them what it's for.

Wolff's recoil calibration kits come with recoil springs and a hammer spring. Perhaps your small spring is a hammer spring.

Thanks, that makes the most sense. I plan on calling Wolff tomorrow to confirm.

Don't know about Sigmas (Sigmae?), but when I buy 1911 recoil springs, they come with a spare firing pin spring.

That little spring is indeed a striker spring and I believe it is factory strength..Good to have a spare and to use if you want to cut a couple of coils for a bit of trigger reduction..Just don't cut too many coils and check for light strikes..
Light strike test:Place pencil in bore and hold barrel up toward the ceiling and pull trigger.If pencil is ejected upward all might be well..
Good luck and have fun..
