I'm looking for recommendations on the best nail gun for framing. I plan to do some small building construction, deck construction and occasional scafold construction. The nails in my finish nailer are not strong enough for this kind of work. Your opinion about the Porter Cable Full-Head Framing Nailer would be appreciated. Finally -- why, besides to confuse the consumer -- does the same company use penney-weight to indicate nail size on its brad and finish nailers and decimal fraction inches to indicate nail size on its Framing Nailers. What's the easiest way to compare (besides looking for the highest numbers)?
