I've only ever had to fix one thing on my Kahr K-98 Elite and that was a magazine catch. They sent me the parts free of charge in about 3 days. Pretty good service.
As far as your gun is concerned... it is new. The sights have about a 10 year life span. The fact that the gun is old enough for the sights to have dimmed doesn't come into account as to weather it's new or not.
