Query: One Homeowners Review

I spend 3 days siding the house and another 2 days building hanging shelves in the garage. The FR350A is powerful and consistant. It only jamed once when the nail hit a metal support -- the jam was easily cleared. I was supprized to find that the gun quits firing with ~10 or less nails in the holder. Slip another set of nails in the holder to continue. I had problems double nailing but I chock that up to inexperience. I am very happy with the FR350A.Note that I took another reader's advice and purchased nails separately (get twice the amount of nails at Lowes for the same price as Amazon). I had no problem finding 2-1/2 and 3-1/2 coated and ribbed nails.
