Every single one of the Hallowell guns is photographed against a Green Felt Backdrop.

Re "suspended", i would say they are resting on some stand, like two pieces of perspex rod that is hidden behind
the guns.

This "raises" the gun off the green felt and therefore the green background is slightly out of focus and the gun in very sharp focus.

Remember, these guys have so many guns going through that they probably have a little set up that is permanent and it just requires dropping the gun onto the set, bang, snap photos and download. The lighting is all done.

One thing with gun photography, you only get better with practice.
