Shame you can't remember where you got it, that looks like a nice model.
For those who can live with something similar, there's always this
Colt M1911 or this one in
Blue/Gold/BlueGold - I don't know if would look better using glossy or metallic paper.
There's also this one from
Smilie, although it's not available yet - looking forward to this one.
And for those feeling particularly adventurous - assuming it's not already linked somewhere here on the forums - there's a
bunch of videos on various firearm paper projects that might be interesting to some people.
Hope that helps somebody.
