Don't waste your money - returning your gas will cost you more than it's worth. Got mine from Lowes. Decided to post it there. I had mt300 (albeit orange and gray). The trigger worked poorly, with only tiny bullets and a bead of glue coming out of the nozzle each time the trigger was pulled. He didn't hold the glue sticks well and made many small notches in them before serving. To use it temporarily I had to inject the glue manually, but the barrel got very hot so it wasn't much fun. I hate that glue gun.
