No I've not come across that before, but then again my experience is limited to my AA510, which doesn't have an adjustable hammer spring. The hammer on the HW100 still has the anti tamper in place, so I thought leaving that at the factory setting would make sorting the power a less complicated fix. There is a split second hiss of air after a shot, I'm now wondering if it's air being lost or just the plenum regaining pressure.

That's exactly what I thought & it's the only reason it's not in the bin
