Who makes the best replacement spring for a SIG 229/.40? Should I get the OEM, the Wolff, someone else?

Also, what weight should I go with? I don't have any problem cycling the slide, so I don't need a low power spring for ease of use. Will a heavier spring protect the frame better or is the standard weight the best?

Thank you.

I have used the standard Sig OEM RS in my P229 .40 since 1996. It handles SD ammo, ball and my mid-range reloads with no issues. Gun has over 48,000 rounds through it and looks nicely broken in.

I use standard weight Wolff in my 1911's. They also handle SD ammo, ball and my mid-range reloads with no issues. I've never owned a pistol that had a problem using the standard weight RS wiith all three classes of ammo.

Here's some Wolff info regarding selection of pistol RS's:

Generally, you'd use a heavier spring for continuous use of hotter (+P) loads. If you used very light bullseye-style reloads you might want a lighter spring.

Thanks. I use range ammo, reloads and a few SD rounds in my gun. Sounds like no need for a HD spring. I don't shoot heavy stuff through them.

Wolfe is fine, I've used many in Sigs, HK's and just about every other brand handgun out there.
