I bought a 2-1/2 angle finish nailer from Home Depot about 6 months ago and hadn't used it until yesterday. Every time I shoot a nail the pusher slips off the row of nails and hangs them up. I had to finish my project with a single shot. I already had concerns with the plastic magazine and wondered how long it would last. Anyone else had that problem. I've had it to long to take it back.
