I wanne replace the plastic recoil spring unit by something more solid, maybe even a tungsten. Now my question is to what spring weight would be advisable i shoot NATO ammo only so they are pretty heavy loaded?

I understand. I pretty much only run A363 9mm ball. It issues a beating on your gun. I have a sprinco recoil reducing in my 17. If you go to sprinco.com the one you need will be listed. Call the contact info on the site and let them know you will be shooting A363 ball. The guy there will tune your reducer specifically for that round. Mine runs great, no issues.
