4.5 lb. Firing Pin Spring/Striker Gen 1-5
4.5lb. Reduced Power Firing Pin Spring
Will work on Glocks GEN's 1-4
This a Reduced Power Firing Spring is for Glocks GEN's 1-5. This spring is manufactured by us Ghost Inc. 4.5 lb. Reduced Power Striker/Firing pin springs this spring will give you the lighter trigger pull weights and is less likely to produce light primer strikes like our 4lb striker spring. Use these only for Target or competition shooting-NOT FOR SELF DEFENSE!! If you combine this spring with the 6.0 Trigger Spring and a Ghost 3.5 lb Trigger you will get a very light trigger pull.
A Key Elemrent for a Trigger Enhancement!

A noticeable reduction in pull weight dropping the trigger weight approximately 1 pound. It definitely smoothed out the triggers on all the Glock action enhancements I perform. This spring is a necessary and highly recommended component of any trigger job!

The Ghost 4.5 spring made a great difference. It dropped trigger weight approximately 1/2 to 1 pound. It definitely helped smooth out the trigger on my Glock 43x.
No light strikes.

Installed it in my Shadow Systems 920L, it made the trigger pull a little lighter and so far 300 rounds and no light strikes.
This is a must !!

Great product. Changed my Glock 43x trigger into a completely different assembly
Fixed a G43 with a terrible trigger.

This in combination with a safety plunger spring was the answer to the 8# trigger pull on my G43. Keep on making good products to fix problems with production guns.

Purchased to replace the 4lb spring in my competition gun due to light primer strikes. This spring is amazing, very light and have not had any issues such as a light strike in over 1000 rds. Have already changed all of my guns over to the 4.5 lb.
G43 trigger upgrade

Definitely made the trigger pull on my G43 smoother, which was the goal. Haven't tested for light primer strikes yet, but the 4.5# spring isn't supposed to cause any issue with that which is why I chose this weight.
For some reason after installing this spring you can now hear the spring during dry-fire practice. It is very quiet and might not be noticeable to most people but I didn't hear it with the OEM spring. This would not prevent me from using it at all because it is VERY quiet.
Trying to dial in my G42

My G42 stock trigger came with a ridiculously heavy trigger pull. I changed out the firing spring and plunger spring to Ghost's reduced power springs. I left the stock connector in. I am happy with results. The trigger feels more in line with my G19 and other glocks. The weapon is cycling normal with no malfunctions. Highly recommend.

Definitely noticable reduction in pull weight using this in conjunction with the safety plunger for the G43x. Highly Reccomended

Helped lighten the trigger. Now my trigger is light sand smooth.
