Is this true about Proud Enchanced Spring for KSC USP Compacts?

So I bumped into this website and found this: http://www.zero-ops.com/kscuspreviewpage.html.

Is it true about this part:

The Proud Enhanced・Hammer spring is a different story, this spring is definitely harder than a 150% hammer spring and causes the hammer to hit the valve knocker HARD. Too hard to the point where you KNOW durability has been compromised. We read a 4 fps gain from the hammer spring alone. The constant use of this spring will eventually damage your valve knocker
assembly, hammer, hammer strut, and hammer strut lower housing.

I think that's the non-System 7, so it's old, but can it still affect the System 7s assuming it is true? Thank you for your time.
