I bought a new SR9c SS this week. I spent time today taking it down and cleaning it. I have two questions. First how many rounds does the factory fire through these before they are shipped. Mine seemed kinda dirty. I sure hope the dealer did not lie to me and it was realy a used one. I also noticed that the feed ramp was very rough. I took my dremel and some flitz and buffed it just a little. It looks good now. Has anyone else noticed a rough feed ramp. After putting it back together I hand cycled rounds through it and they went through smoothly.
