After how many rounds do you replace a recoil spring? Does that amount change depending on the gun or not?

You do not need to replace any springs unless something happens to them. So in most cases the springs are never replaced.

Some owner's manuals recommend certain springs be changed at specific intervals.

Usually when the used recoil spring is 1" or more shorter than a new one.

If buying a used firearm, sometimes it is worth the cost to replace all springs for piece of mind.

It can depend on the pistol. For example, recoil springs on the 3" & 3-1/2" 1911s are recommended to be changed more often than the 5". I've read as low as 500 rounds for the 3" & as high as 5000 rounds for the 5".

Personally, I suspect these round counts are on the conservative side & if it's just a range gun, maybe have a spare on hand & don't worry about it until it stops feeding properly. For a SD pistol, what's the cost of a spring when compared to piece of mind?
