Toni Firing Pin Spring (Glock / P-10)

Reduced power firing pin spring.

Optimize your Glock’s performance with precision-engineered firing pin springs, available in three different weights:

• 3 lb – Ideal for polished strikers and very soft primers, this ultra-light spring delivers minimal resistance and is suited for fine tuned setups.
• 3.5 lb – Designed for competition use, it lightens the trigger pull while maintaining excellent primer ignition.
• 4 lb – Perfect for shooters seeking a smoother trigger without compromising reliability in various conditions.

For the CZ P10 model specifically, we suggest using either the 3.5 lb or 4 lb versions to ensure optimal ignition and operational safety.

How it works.

As the trigger is pulled, the Firing Pin spring (7) is compressed until the firing pin is released, at which time it drives the firing pin towards the cartridge. The Reduced Power Firing Pin Spring reduces the force against the trigger. (It also reduces the primer strike force, so should be used only for competition or well tested ammunition.)
