I think either the pistol grip and 22 inch barrel, or if you want a straight grip, go with the Cowboy with the 26 inch barrel. I have the Cowboy, and it is a very light rifle by my standards, 26 inch barrel not withstanding. The longer barrel gives you more sight radius which translates into a better sight picture with iron sights, and also gives you NINE rounds at hand. Eight in the magazine and one up the pipe.

Either rifle is a great set up. If you shoot irons, be sure to change out the standard barrel sights for a rear ladder and a blade.
