Glock Gen 5 Firing Pin Spring Cups available for all models
FAQs
Spring cups are small internal components that secure the firing pin spring in place. They’re essential to maintaining proper striker tension and safe, consistent ignition in your Glock.
While not a high-wear item, damaged or lost spring cups can cause ignition failures. Replacing them is a smart move during slide rebuilds or firing pin upgrades.
Install steps vary by part. NDZ recommends having parts installed by a certified armorer or qualified gunsmith.
