I just ran across this cool site Brickarms.com, they sell custom Lego compatible weapons. They also have custom World War 2 German soldiers and custom Lego K9 units! I purchased an armory for my son to make his own custom Legos, and bought a custom lego German soldier. These World War two custom Legos will go perfectly with Indiana Jones Legos.
Here is a Brickarms custom Lego sniper:
