    Worked as intended

    The TTI Ultimate Glock Plunger Spring, in tandem with the TTI Ultimate Glock Gen 5/Glock 43 Trigger Return Spring, brought my trigger pull down from 6.5lbs to 5.25lbs. Feels very clean, no function or reliability issues to speak of. A good way to drop trigger weight without sacrificing reliability.

    Significant difference

    Gen 5 glock triggers have greatly improved. However these springs just take it to true perfection.
