~ 2000 Tri-nozzle failure seems to be due to pumping too fast.

10)Notes and Comments
Good shotgun, but the tri-nozzle is an achilles' heel. Mostly plastic construction (only large metal parts are the barrel and pump assembly) is robust, but easy to work on.
Practically guaranteed to break eventually...
