good tool, have had no problems with it for several years now, I'm a handy man, not a full time roofer.

Brand spanking new. Reliable.

As a contractor I shingle several houses a summer, This gun is what I have had best luck with, rarely jams, lasts a long time, would highly recommend. I have 3 others & they all still function well after several summers, I have one that is just the 450 version and not the XP and I wouldn't go with anything except the 455XP

Bought this gun as a back up gun. Since then it has become my main. I love it's ease of use. I have the contact actuation trigger which enables me to fire rapidly. Handles similarly to a hitachi. I've used the hitachi, bostitch, porter cable, Bosch and master craft and this is by far my favorite. The Things I wish we're different are the depth gauge isn't numbered like the bostitch to allow for instant setting. The bostitch is unique in that feature I find. And the coil load is a two step (two lids close over nails to load) unlike the bostitch and Bosch which only have one. These are more ergonomic features that contribute to a few seconds here and there but not to the quality of the gun. I would definitely recommend this gun and I would buy it again.

I bought this gun to put a new roof on my house. I was able to go at least 3 times faster than hand-nailing. The only problem I had was when the gun jammed. I'm pretty sure this happened when the roofing nail hit the head of a nail holding down the roof sheathing. I had to remove the jammed nail with pliers. I even dropped the gun once onto the driveway and it still worked perfectly.
