There is alot of things that can be done to the glock trigger most cost money. The cheapest thing to do is learn how to properly shoot it. When making another shot do not let the trigger go all the way forward on the gun(unless of course you are transitioning to another firing point). Only let the trigger go forward roughly 1/4 of the way. Just enough for the trigger to reset and fire again.First Glock.Factory stock internaks. Been searching trying to determine which connector to buy. Will be satisfied with 3.5# trigger but how do you get rid of the beginning slop?
