I'd ask for the big Desert Eagle. I think this year or maybe 2014 is the big anniversary of the IMI(Israeli Military Industries) Desert Eagle.
The firm is now owned by Kahr Arms & they updated the Desert Eagle line about 2/3 years ago. I'm left handed & wouldn't mind buying a .50AE pistol just as a safe queen.
Id get a .44magnum Ti version to shoot.
Those huge mothers aren't easy to use if you aren't in shape.
They are very popular in US video games & Hollywood productions.

PS; as another TFL member noted, you can get a .44 barrel & shoot both calibers out of a Desert Eagle pistol.
