Recoil Spring Replacement Testing
I have a 229/.40 that I probably have 2500-3000 rounds through. It was a CPO gun when I bought it, so I assume the recoil spring was new at that time.

I have heard that 5k rounds is a good replacement time for springs.

Is there any way to "test" a recoil spring to see if it is still operating to spec? I understand that they aren't particularly expensive, but I don't want to be wasteful either.

Thanks for any insight.

Play it safe and change it.

Most SIG springs I would just compare to a new one. If it’s much shorter than new, I’d toss it.

5K is the number of rounds specified in the armorer's course.

Thanks Jerry. That's a useful and practical way to look at it. I've got a new one I can check it against.

It is amazing at how much it can compress with just a thousand rounds through it. I always get a few of them when I order and keep them hanging around. Like others have said, it is cheap insurance.
