Query: Try Hitachi

** See my review of the N89C as wellI bought a N80 and it would not drive a 3" or a 3 1/4" galv. spiral nail into Douglas Fir. After sending the gun in to see what was wrong with it. It was send back with nothing wrong. I took the gun, the nails, and the wood to the Bostitch distributor. They could not get it to drive the nails. Even the new one they pulled off the shelf did not do it. They gave me a N89. The depth adjustment on the N89 is nice and it has never jambed. Changing nail sizes is much easier then the N80.Both the N80 and the N89 double fire easily. I have listen to nails land 50-60ft away on the street.The crew framing my house uses 4 Hitachi NV83 guns. Thees guns are more balanced, drive 3 1/4" nails no problem, and I have not had a double fire yet. The Hitachi guns run 3-6 coils of nails a day 6 days a week in the mud and sawdust. If I ever wear my N89 out I'll be spending the extra $$$ on the Hitachi.
