Easily hammers 2" nails halfway to China. Had to drop the air pressure to 50psi and set the depth control to the bare minimum to flush it out, so definitely plenty of power. There were no traffic jams, although only about 50 nails were driven in. Only complaint is that it's quite larger than my 18 gauge nail gun, loading is a little tedious compared to older guns but not the worst. The crazy pencil sharpener belt hook combo should be replaced with a decent sturdy hook, I mean I don't think I would trust climbing stairs with a belt hook.
