Query: Dissatisfaction of Staple Gun

The staple gun I bought to build a house about a month ago will not accept the staples; I have to push on the plunger in order for the staple to go up to the head--I am very dissatisfied with item and I do not have time to replace before the house is finished. Will never purchase any other any Dewalt Product. I have also been using a used Bostitch and it has not misfed any staples at all. Harry Presnell-Tennessee
