I need to replace my 938 springs in both 7 and 6 round mags and I’m curious about two things:

Are Sig OEM springs the best choice or are there better?

Do you always keep your mags filled to capacity?

Thanks!
Jim

They’re 938 mags.

I always use wolff extra power springs. Not sure if they make any for the 938.

And I always leave my mags fully loaded. It doesnt hurt the mags. What weakens them is constantly loading and unloading the mags. Think of it this way. How many times can you bend a paperclip before it breaks?
