paolo.orange; Instead laying the Luger on the belly, I prefer to use the other side of J.L, where you will find a much nicer rack to place it in.
..that will help it 'stand up' and reduce the plastic reflection from the background
In danger of being 'old school', the circular polar filter would help remove the yellow reflection without taking it to Photoshop.
But if it has been captured that way, I would consider to use 'clone brush'. Where you can right click and set a reference point, then edit as little area as possible in a non-linear way. On the magazine, they darker line would be a natural referance point, set as close as possible.

It is possible to Google up much the same for Pain Shop Pro. That program is a little more easy to use than Photoshop, but has become almost just as advanced.
