This reminds me, everyone who takes pictures of their guns should look at this thread

The big things you need to do to get awesome pictures of guns are:
1: rule of thirds
2: find a cool background that contrasts the gun well (the pic above is black/textured black on textured black and the grips are practically the same as the foam)
3: extremely low depth of field, low exposure, handheld light (move it around to get all angles, but don't get in the way of the camera,) and a really long exposure time (so you can move the light around)
4: start by white balancing the camera and correct the balance after you take the picture.
