Does Sig, or any of you experienced in Sigs, have a recommended round count in between replacing major springs on a Sig Pxxx series handgun? Just picked up a used Sig P220, was a police trade-in, their armorer cleaned it up before sending it in, but that's it. Round count is unknown. Thanks!

A common rule of thumb is every 4-5000 rounds. If round count is not known and suspicions are that it may need new springs I would go ahead and change them out. You can order a spring kit for your particular model from Sig and it includes the necessary springs. I usually keep at least a recoil spring on hand for each of mine.

[img]http://*************/groupee_common/ver126.96.36.19930/platform_images/blank.gif[/img] Posted February 22, 2009 09:38 AM I believe this may still be of interest (original information from March 2008).
The following is SIG SAUER's current parts replacement schedule (numbers of rounds), with some comments of my own:
Barrel: If the pistol exhibits keyholing or unacceptable accuracy.
Decocking lever spring: 10,000
Extractor spring: 20,000
Firing pin: 20,000
Firing pin spring: 20,000
Magazine spring: When magazine fails to lock the slide open. *
Recoil spring: 5,000 â€*
Roll pins for breechblock retention (pins, HD): 5000
Safety lock spring: 20,000
Slide catch lever spring: 10,000
Takedown lever: 20,000
Trigger bar spring: 10,000
Mainspring (hammer spring): SIG SAUER evidently makes no formal recommendation about the mainspring, but lbj was told by customer service that guns with 40,000 rounds are still igniting their ammunition with the original spring. If ignition problems do develop and can't be determined to be due to other reasons, the obvious course would be to try a new mainspring.
* I also recommend replacing the magazine spring when ammunition is not held securely. This can occur before slide lock failures.
â€* I had seen an early recommendation here that the recoil spring be replaced after 3000 rounds, and that's what I follow.
For the armorers: SIG considers the extractor used in P220 stainless steel slides to be a "sacrificial" part, and that it should be replaced after it's removed from the slide.

Im sure a round count is a good way to maintain your Sig to change springs.
Im of the thought if it works I dont mess with it.
BUT that is why I practice at the range with my carry guns to keep an eye on them
Top Gun Supply is one of the better places to order you Sig Parts from.

In a nut shell, yes. I would be more concerned about reliability especially if it were a carry weapon. Degredation of performance = less reliability.
