This product was very disappointing, it was not manufactured correctly and the front is so off center that I am afraid it will break in use. anticipating the wall thickness of the material is an eighth of an inch on one side and just under 16 inches on the other. I have had other high quality Senco nailers made 10, 15 or 20 years ago. Production and quality control have changed dramatically and they have probably moved most of their products, like this equipment, overseas.
