I like to build my own triggers. I use a stock trigger shoes with a hi polish trigger bar . Then the 3.5 trigger connecter then the reduces spring and soften safety plunger spring . And hi polish to all parts to help movement. Now all my glocks but one are around 3.5 to 4 lbs trigger pull. But one is 2.5 or 3 and I love that feel . I feel it puts me on target faster .
