I've installed the Wolff striker spring in my gun, but haven't messed with the action spring, as long as the gun is running.

Yes, the line between too little and enough recoil is small!

I doubt you can discern any wear in the few rounds you have fired or after 1000.

Wear marks and even slight wear are "normal". Do be aware and consider that your are dealing with a 30+ lb spring in your pistol, with the same ammo that was used in the early 1900 leaf spring design, the spring with less than half the resistance of the coil spring set up. Which caused closure reliability problems, and is the reason for the coil spring coming into use.

I think you are worrying too much. JMHO.

PS: The wolf striker spring is stronger than it needs to be also, and the small tab on the spring retainer will experience excessive wear as a result, IMO and experience. it is very small in area and will benefit from use of the weakest spring that gives you reliable primer ignition; and frequent lubrication.
The original design strength was for "hard" military primers, and is not necessary for commercial primers. Something else to think about.
