Zev Adjustable Fulcrum Trigger Drop-In Kit fits Glock 4th Gen

Adjustable Fulcrum Drop-in Trigger kit allows you to adjust the trigger and weight and greatly enhances the feel of trigger pull. Kit does not come with the Firing pin. ZEV Technologies recommends this for competition use only. Requires one tool (a standard 3/32nd punch) and 15 minutes of your time. Trigger weight can be adjusted to as low as 3 pounds. Lighter pull weight requires less pressure reducing trigger fatigue and improving accuracy. Pre-travel and over-travel are adjustable to allow for a shorter pull crisper break and faster reset.
