I'm a fairly new Rami owner. My plan is to just pop out the carry spring when I go to the range and put it back in after I clean her up later. The CGW site has a recommendation of 1000 rounds for EDC pistols and a smith at CZ USA offered 500 rounds as his OPINION. As far as I've seen CZ has no official recommendation.
I have two Kimber models that both have 1000 rounds listed as the change interval for recoil springs. The smaller Micro .380 was originally equipped with a round wire spring. I had several of those springs flake out in the 500 round range. Kimber has since redesigned the guide rod and now has a flat wire spring to go with it (a tremendous improvement). The suggested change interval is still still 1000 rounds. On my larger PRO (4") model I've upgraded to a Wilson Combat flat wire kit, it's supposed to give a 10x greater lifespan, never had a failure with that pistol old spring or new. We'll see how long the spring goes?
Point is recoil springs are something to be aware of on ANY semi automatic pistol. Once you've got a handle on the specifics of your model you're good to go :-)
