Legacy Manufacturing introduces the Lock-n-Load Quick Connect Grease Guns. Featuring a threadless quick connect barrel, Lock-n-Load technology significantly reduces user downtime when compared to conventional threaded grease guns. This grease gun eliminates cross threading and priming problems, simply slide the Lock-n-Load switch to disengage or reconnect the barrel.  The special locking feature eliminates accidental disengagement. Lock-n-Load also features an automatic bleeder valve that bleeds air ever time the barrel is connected to the head.  This significantly reduces air locks and priming problems.
