Just got back from the gunshop. I picked up a Kimber Grand Raptor. I really like it and hope to hit up the indoor range tonight to try it out. I bought a Springfield Mil-Spec a few weeks ago and returned it toward the Kimber. I was just having problems with the Springfield feeding sometimes. Anyway, I hope I have great luck with this. In this last picture it looks like there are brass marks behind the ejecton port. Do you think the gun was used, or are these from test firing at factory. The gun was in the ziplock blue bag, but the orange safety thing that holds the slide open a little was removed. Just wondering if I should take it back to exchange it or if it's fine.
