Denny thats why i dont use a gun just put the nozzel inside of a brass fitting when i want to stop sanding i just unplug the air iv gotten real good at it and gotten fast at clean up and yes these blasters are all the same it seems ive used the same nozzel for at least 5 bags of sand and im sure it will go 5 more but my hose may need replacement soon i may just get another blaster for parts good luck
