I was a carefree 23 year old at the time and can't imagine I would have spent over $400 (well over two months rent) on a gun but you never know. I probably put it on a credit card and paid the minimum until it was paid off.
The serial number BEJ5xxx means that it was manufactured in 1989 but the wood grip that came with it has July 1990 stamped inside. Why the discrepancy?
edit: BigJim, it is a common stainless 4" model.
