Generally, two schools of though on recoil spring: 1) change after a fixed number of rounds, or 2) wait until there is a problem and then change. I prefer the first. If you've gotten 14k rnds on the one installed now, it probably needs changing. Also, the replacement may not last as long.

Extractor and slide stop. My experience is both will eventually break and they don't break at anywhere close to the a fixed time. The extractor will last longer than the slide stop. If you have 20k rnds on a slide stop and are going to shoot a major match, replace for the match and go back to old one and use until it breaks. Extractors for me have lasted >27k rnds on average. Ditto for major match in extractor is close to 25-30k.

Trigger return springs also falls in the the same category as extractor and slide spot. However don't have my maintenance records with me so not certain on pulls before breaking a TRS. Also, dry fire is the same as shooting the pistol re this part.

YMMV
