What is the correct recoil spring for a folded carbon slide P228? TGS lists a Wolff replacement for the P225/P228/P229 as well as an OEM white spring for the P229/M11-A1; but not an OEM P228 spring. I was fortunate enough to locate a new OEM SIG P228 spring for my pistol (KE P228), but with the new spring installed I can feel a crunching sensation when I fully retract the slide - as though the new spring is binding or bunching up upon the recoil spring guide. The pistol does not do this with the used P228 recoil spring nor with the new white P229 spring. As you can see from my photo both the used P228 spring and the new P228 replacement are one (1) coil longer than the white P229 spring. With the same number of coils, I would expect the compressed length of both P228 springs to be the same. Has anyone else experienced this? Thanks for your thoughts.

I believe a 228 should use the same spring as a 9mm 229, which would be the white one last time I ordered one.

I have an older list with different part numbers for the P228 and 9mm P229. I always assumed that was because of the slightly heavier 229 slide. The list indicates the part numbers for P225 and P228 recoil springs are the same. That said, I suspect that a 9mm P229 spring would work just fine in a 228.

I have correct P228 recoil springs but unfortunately they have old part numbers because I ordered one in a parts kit in 2009 and two separate ones in 2009 and 2010. That part number was 34225490 and it is supposed to be for a P225 also, as sigfreund mentioned.

However, I ordered a P225 parts kit (Made in USA) in 2017 and the recoil spring in that kit is about 1 coil longer than the old P225/P228 ones that I have and is probably the same length as your new P228 spring. I don't have a 9mm P229 recoil spring, but my correct P228 spring is about half a coil shorter than my blue tip .40/.357 P229 spring so I think I too would go with a 9mm P229 spring as has already been suggested.

The P228 recoil spring is a little stronger than the P229 9mm spring and the P228 spring has about one more coil. This also means that the P229 9mm spring is weaker than the P228 recoil spring.

When firing carry or full strength or plus p rounds in the P229, I cut one coil off a P228 spring and use it in the P229. Midwest Gun Works has a 3 pack of the P228 springs with no paint.
