^Didn't think of that.^ The impact could have messed up something in the ASA internally and is starving the gun.
I would go ahead and strip the gun from top to bottom. Egos and Eteks are pretty simple to figure out. Most of the time it's something simple like an oring, battery, pinched/clogged/loose hose/barb, or the occasional bad QEV diaphragm (in guns containing them).
