This Glock Worx Fulcrum is the finest trigger available for the Glock .45 GAP! Complete drop in installation requires no special tools, or the services of a gunsmith. The CNC Billet Aluminum trigger pad has an ergonomic shape with a wide flat face that is ideal for shooting with the pad of your trigger finger as opposed to the rounded face of the factory trigger. The trigger safety of the Fulcrum is 3x wider and more flush when depressed. The trigger safety also features a real spring as opposed to the thin plastic nubbin of the factory safety for greater heat and chemical resistance. The Fulcrum trigger features adjustment screws for PRE and OVER travel. Range of trigger movement can be shortened to ¼” overall, with all factory safeties intact. Trigger reset has been shortened by half so that pistol can fire mechanically faster. The trigger bar is high polished and precision ground to help eliminate trigger creep and allow the trigger to stack up and break consistently.
