I haven't watched the movie yet but I am planning to tomorrow. Said to be one of the best Bond films ever made, "Skyfall" surely packs a lot of action as I've seen in the trailer. You'll be interested in what firearms were used in the movie, apart from the familiar Walther PPK and suffice to say they have their airsoft versions and Wolf Armouries have made their research and found out that they have these in stock.

So if you want to find out what these are, better go to the Wolf Armouries website.
