I ordered these on Friday evening and they were delivered on Monday! I have had several other nail guns but this is my first Bostitch. It was easy to load and easy to adjust to drive 2" galvanized nails into 1/2" OSB, driving each nail to the perfect depth easily and evenly. It comes with two triggers: a pistol-mounted black trigger and a gray sequential fire trigger that you can easily replace with a single trigger if you wish. The default black trigger works great for me as you can still place the gun exactly where you want and then fire once when accuracy is important. I've read that the trigger can shoot two nails in the same place if you don't let it bounce a bit, but I haven't had this problem so I'll probably stick with the black trigger. That way I can still shoot at close range when speed is more important than precise placement. I recommend this gun to anyone who needs a medium sized nail gun that can use spiral nails up to 2-1/2 inches in diameter. It is best used to install sheathing, fencing and siding including fiber cement products such as Hardie Board.
