this bag be rugged and large enough to easily fit my Hitachi Framing gun without any trouble . there be even room to put some other loose tool on top if you wish\/need to . the strap a tough and the correct size to carry over the shoulder at waist height . I be very glad I get this to help offer some protection to my frame gun -lrb- especially when load it into the truck , you know how everything end up pile on-top of everything else -rrb- . the only thing that could be better would be for frame gun to include hard case when you buy they -lrb- I do not know any maker who do so -rrb- . I highly recommend this product .
