Gun shoots EXACTLY every other time. I keep it oiled and am using 2" Porter Cable brand brads. I lost the nose cushion, could that create a problem? Total usage is maybe 3 clips of nails, but, it is way out of warranty.
Sometimes my nailers (regardless if size) will do that. It has been something in the feed mechanism exactly one time, and off sized fasteners all the rest.
Make sure your feed mechanism is very clean and that the ways on the magazine are as well. Try another brand or batch of brads and I'll bet your problems will go away.
Unless I am concerned that I am buying nothing but trash, I don't pay that much attention to brand names anymore, especially one like Porter Cable. They all use jobbers to make their products and almost all of those consumables come out of the same place with a different label.
