..and downing a yogurt, I find a green painted recoil spring with about 13 coils. I assume that is for my P220 (mid 90s German) or my 226 9mm. Correct?

Also there is a red painted spring with about 9 coils. What does it go to?

My Sig collection - P220, newer 226 above, 228 mid 90s, 225A, 239T (two of them).

No Glocks. But I do have a PPQ.

My KE W.German p220 came with a double stranded green recoil spring just like that.

Red would be for P220 carry. Green P220 and P226 40/357. P226 9mmm takes orange spring.

My 220 is a KE too. The 228 is KD.
