Being an HK newbie, I did NOT realize that the hammer spur on my new USP 45 is RUBBER! What is HK's thinking behind that? Anyone ever seen one that had broken or torn away? Like from being dropped or something?

The rubber hammer spur was added circa 1995-96 to act as another measure of prevention against accidental discharge due to dropping the pistol on the hammer.

As far as I know the hammer has had the rubber part. I assume it is to get a better grip on it when thumbing the hammer (or the reason in the post above mine). Never heard of an issue with it coming off. If there was an issue, HK would not product it like that; just not their style to put things out with inherent design flaws.

Feels like the p30 is steel with a rubberized coating on the spur area, can anyone confirm this?

My USP 45's hammer spur also feels like steel with a rubber coating, but if you gently apply pressure sideways, it will deflect some. I think it is mostly a really hard durometer rubber, possibly with a small steel "core".

I once asked this question before and the general consensus was to protect the hammer in case you dropped the firearm in such a way as to land on the hammer itself. Rubber cushions better than metal.

It is rubber. Unfortunately, the spur of my USP9f (BB code) is recently folding down too much during manual cocking thus making it a bit difficult.
I'm really afraid it is going to be torn away soon.
Could it be caused by too frequent manual cocking (during dry firing)?
Should I send it to HK for replacement?
In terms of this issue - how about USP's reputation "built like a tank"?

The Leopard 2 has a torsion bar suspension, and has advanced friction dampers. The running gear consists of seven dual rubber-tyred road wheels and four return rollers per side, with the idler wheel at the front and drive sprocket at the rear. The tracks are Diehl 570F tracks, with rubber-bashed end connectors, which have removable rubber pads and use 82 links on each track. For use in icy ground, up to 18 rubber pads can be replaced by the same number of grousers, which are stored in the vehicle's bow when not in use. The upper part of the tracks are covered with side skirts, with the first two road wheels and idler covered by an armoured skirt.

Yes, it's built like a tank...

I think it's for or as a "Non Slip or "Slip Resistance" type hammer.

My Mark 23 had the same problem. I got pretty bad but never actually came off like I thought it was going to. It did become enough of a problem that the hammer wouldn't fall correctly. The rummer part had wobbled sideways enough to hit the rear of the slide and prevent the hammer from hitting the firing pin. I called HK and told them, they offered to replace but I had them mail me the hammer and I replaced it myself. You would think they would be a little more durable but whatever.

The situation with my hammer spur is not as bad as it was been in your MK23 but I'm a bit troubled as I did not expect such an issue with USP. Though it's still possible to cock the hammer and still no problems with firing pin hitting I think I'll call HK in order to replace the hammer.
One more question - can it be replaced with all-metal one by HK as a part of warrant service?
