I'd replace the recoil spring.
The other springs usually don't deteriorate, and there's no reason to replace them.
I'd use factory-spec springs.
NO ONE knows more about a gun than the company that made it, and people who insist on playing around with springs often compromise reliability or durability when they use non-spec springs.
To add a layer of protection, use a GOOD synthetic shock-buff on the recoil spring guide for practice shooting.
These are cheap, and do pad the impact of the slide hitting the frame.
DO NOT use a recoil buffer if you carry the gun for defense.
These buffers have a tendency to come apart and can cause jams.
Next, stick to standard loads of 230 grain ammo.
Hot ammo, or lighter bullet ammo can be harder on the frame.
