Nicely done! But I'd hate to render my 1911 (the economy M1991A1 model) inert. It would be interesting to see other pistols done this way - a P08 Luger perhaps, and an 1896 Mauser.
Remember, a traditional non functional "cutaway" isn't a firearm and makes an excellent home for your spicy parts, the ones that aren't any kind of drop in auto something or other, you know the thing.
