I was looking at the Ruger Mark III Standard from the local gun shop, but I noticed that in the box, there was only 1 key for the internal safety lock. Aren't there supposed to be two keys for the safety lock? Also, one of the magazines seem to be scuffed as if it was used. What's with that? Could Ruger or the shop swapped out the new magazine for an old one? How can I tell? I really want one, but I might not get a chance if I wait too long.
