Putting it over my support left shoulder useing a 3 point sling seems to work best for me being right handed. But you could use it that way too.

This is patrol or Israeli style (read lazy ) Three point slings are obsolete with more advanced two point slings on the market. The correct way is what Stalker said, over the strong shoulder under the weak arm.

The sling linked to in the first post is two point.

The sling in the picture above is three point.
