2). A 6.0lb Extra Power firing pin spring. (Longer)

Spring Kit Comparison
The 4.0lb Reduced Power Striker Spring used with the 6.0lb Extra Power Trigger Spring and Reduced Power Plunger Spring is ideal for target, range and competition shooting. This kit should NOT be used to carry pistols or Self Defense purposes.
The average pull, when paired with a 3.5lb connector, will be approximately 3.0lbs
The 6.0lb Extra Power Striker Spring used with the 6.0lb Extra Power Trigger Spring and Reduced Power Plunger Spring is a great choice those looking to improve, lighten and clean up their trigger pull but still need reliability for carrying.
Also an excellent choice in 10mm and 45ACP models as both have a 10% heavier firing pin than the smaller Glocks that can fatigue a reduced power spring faster.
The average pull, when paired with a 3.5lb connector, will be approximately 4.0lbs
