Off topics: Yes, his writing made my eyes bleed.
On topic: Invest in a sling if the gun is too heavy. My first game I carried a gun for the whole night and could barely raise my arms to drive home at the end (although lack of sleep might have been a factor there). It's much easier to support the weight on your shoulders than in your hands.
The weight from your rig will probably be more than your gun. If you want to be a sniper, and I use the term loosely, you might want to consider the added weight of a ghillie suit and the conditions while wearing one.
Edit: Why would you want such a large pistol if weight is an issue? Surely a smaller one would be lighter and better suited to your needs.
