Ditto on the 25 cent trigger job , polish all the metal to metal contact surfaces with flitz to a mirror finish on the trigger and trigger bar, Firing pin safety, locking block , trigger connector, the four metal tabs where the slide rides in the frame at the front and rear, and the firing pin. That will smooth up the action and trigger considerably and shave usually about a pound off your trigger weight. I do it to every new Glock I buy , if you wanna go further than that you can buy a lighter trigger connector from lone wolf
