Glock Gen 5/42/43/43X/48 – Trigger Return Spring – 25% Extra Power
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The IronKells 25% Extra Power Trigger Return Spring is a drop-in trigger spring upgrade built for Glock Gen 5 pistols and slimline Glock 42/43/43X/48 models. It replaces the factory trigger return spring with a stronger spring that is designed to increase return force, speed up reset, and smooth out the pull without turning the gun into some fragile race-trigger science project.
This is a smart upgrade for defensive builds, tuned EDC pistols, or anyone wanting a cleaner trigger feel and more assertive reset while keeping the setup practical. It is the kind of small part that can make the gun feel more awake without needing a full trigger overhaul.
Fitment
- Fits Glock Gen 5 trigger housings
- Fits Glock 42, Glock 43, Glock 43X, and Glock 48
- Built for Glock-pattern trigger return spring applications in the supported models above
Does NOT fit
- Does not fit Glock Gen 1–4 trigger housings
- Do not assume fitment for non-Glock platforms or unsupported aftermarket housings
What it does
This spring adds roughly 25% more return force than OEM. In practical terms, that can help produce a stronger reset, reduce sluggish trigger return, and slightly lighten perceived pull weight in a properly matched setup. It is a small part, but it directly affects how the trigger feels coming back forward under recoil and during fast follow-up shots.
Why it’s worth it
Some trigger parts are all drama and no payoff. This one actually does something useful. A stronger return spring can make the trigger feel more positive and more responsive without forcing the buyer into a full competition-only build. For tuned carry guns and practical range setups, that makes this a cheap upgrade with real-world value.

Verify before you buy
Verify your exact Glock model and trigger housing generation before purchase. This spring is for Gen 5 and the slimline 42/43/43X/48 family only. It is not for Gen 1–4 housings.
