Don't waste your money - it'll cost you more in gas to return it than it's worth. Picked mine up from Lowes. Figured I'd put this out there.
The one I got was the mt300 (orange and gray though). The trigger didn't work well with only tiny beads and a small string of glue coming out of the nozzle
on each trigger pull. It didn't grab the glue sticks well and made many tiny notches in it before it would feed. So to temporarily use it I had to push the glue in manually -
but the barrel gets extremely hot so it was really not fun.
I hate this glue gun.
