My thoughts on this...
I understand that this fellow probably just didn't have any better way to hold the gun for photography and just plain didn't that anyone would see this as being a horrible thing to do to a gun.
That said, what a horrible thing to do to a gun. Even if this didn't harm it in any way, what kinds of things does he do to guns while not taking pictures of them? He probably didn't see anything wrong with this practice. Then again, I know people who don't think pointing the muzzle at you ("But it's unloaded!") is such a bad idea either...
