Magazine springs for 3913TSW pre-rail?

[KCabbage]

Hello,
I finally got a hold of a pre-rail and while the springs seem strong I am curious where to find new ones. I checked Wolff's but the ones they seemed to have where for 8 round magazines and the pre-rail holds 7.
Where do you find new ones?
Thanks a bunch!
Take care

Have you tried Brownells? They should have the factory springs.

I never did compare the two when I had both guns. I would almost assume they were the same. You can just call S&W and ask them if they are, and get the part number if you don't want to order from them.

Good call, thanks!

They use the same spring for both the 7rd and 8rd mags(CS9). S&W part #20165.
