I just wish that all honest contractors had compact nail guns. I keep hearing this story, sad story, every day.
"I was at my job doing some framing with my nailer and the gun stopped working. I attempted to unjam a nail, but it was not jamed. The gun would not work. I then thought that maybe my compressor got un plugged. I went to the van/truck and found that my compressor was just stolen."
Get rid of the hose and compressor and have the gun with you all times.
