I'm trying to match up a impact wrench that will work good with this compressor. I've tried a few and they don't seem to have enough power. I have an older Ingersoll rand and that one works great, but something is wrong with the inside of the gun. I've tried cheaper guns like a craftsman gun and a coleman powermate. They didn't work so well. The compressor says it can run a impact just looking for some info on a good gun.
