Stanley-Bostitch RN46 3/4-Inch to 1 3/4-Inch Coil Roofing Nailer
This is the only nailer on this list with a dry-fire lockout; a feature that I think every nailer should have. With it, you avoid damaging the tool by trying to fire a shot when there are no nails in the magazine. The magazine housing gives it a 4.8 pound weight, just a shade more than the Porter-Cable. But the really great thing about this nailer is that its backed by a 7-year limited warranty. Like the others, it has a tool-free depth of drive adjustment, wear guards, and pads on the side to prevent slipping.
