I bought an xd9sc on Gunbroker this week that was said to be 90% but definately not the case and for the price I didnt expect it to be aswell. The slide is a bit more grey than my 4" 9mm and doesnt seem to be that worn to be loosing the finish, is that normal for some older models? I am thinking the age is 4 or 5 years maybe because of the serial numbers starting with "US". My biggest gripe or worry is the trigger has been grinded smooth and rounded on the place where the finger rest which makes me wonder what else might have been altered, I am a bit cautious to even want to shoot it till looked at better. I am thinking it has a few thousand rounds thru it atleast and have been looking at the videos to change the trigger out with a PRP Ultimate kit when I can afford it soon, is there anything else you would look for? change?
