I see this all the time. Guy buys a 45 XDs, never fires it, & when the 9mm version comes out, he thinks our store will make an even swap. Even though the 45 is unfired, it is not new, as it's ser# is already on a 4473. He totally flips out when we tell him it's going to cost him at least $150 to "swap" guns according to the formula I used earlier in this thread. When I asked him why he bought the 45 if he really wanted the 9mm, he replied the 9 wasn't available when the 45 came out, & he had to have a new gun. I asked him why he couldn't hold onto his money until the 9mm came out. His reply was he'd have pis#ed it away on something else, & had to have a new gun that day, even if it wasn't exactly what he wanted. Any other gun store employees here who see this all the time? GARY
