The details on that one look close enough (to anyone who's not a gun enthusiast) to a Colt 1911, which you can find replicas and toys of all over for very little. Should be able to get a rubber training version if that's what you want, and they sell air soft 1911s on eBay for around $10 if you want something more detailed.
