Don't take this the wrong way, I mean no disrespect, but if you fired any rounds out of that weapon, let alone 30 then it is not longer considered NIB by anyone that knows anything about firearms. You can very much use the term LNIB (Like New In Box) but once it's been fired even once other than at the factory it becomes a used pistol. And BTW that price is really good, I'd buy it if I hadn't just spent money on a rather large safe. Oh yes it would help a lot, seriously, if you took some pictures and posted it with your offer. If you do take some pics, please post them to a Photo Hosting site like SnapFish, or Photobucket and then paste the link they give you to your post.
Welcome to the Forum, Hope you'll stick around and participate in the forum, If you do I'm sure you will have fun and learn new things, or even teach someone something new, and best of luck with your pistol. Actually may I ask why you are selling it? It's a great pistol, and very accurate.
