GHOST INC FIRING PIN SPRING 3-PACK (GLOCK GEN 1–5)
CONTROL YOUR TRIGGER’S SOUL — 4lb, 4.5lb & 6lb
This isn’t a grab-bag. It’s a tuning kit. The Ghost Inc 3-Pack gives you three calibrated striker springs — 4.0 lb (light), 4.5 lb (balanced), and 6.0 lb (duty) — so you can swap, test, and lock in the exact striker tension your Glock needs. Whether you’re building a paper-punching race gun, a reliable patrol hammer, or a no-nonsense carry piece, this pack lets you dial it in without guesswork.

SPRING WEIGHT BREAKDOWN:
Know your setup. Run it right.
| Spring | Ideal Use | Pull Impact | Primer Ignition | Forge Files Notes |
| 4.0 lb | Target / Competition Only | Lightest | Weakest | Combine with a 6.0 lb trigger spring and 3 lb - 3.5 lb connector for ~2.0–3.0 lb pull. NOT for carry or duty use—light strikes possible on hard primers. |
| 4.5 lb | Range / Hybrid Setup | Light | Weak-Moderate | Good balance if you’re pushing light but still want to avoid Russian ammo failure. Add a polished striker for max results. |
| 5.0 lb | Everyday Use / Mild Upgrades | Moderate | Factory | Great with mild connector upgrades or trigger polish jobs. Glock-standard power. Boring, but it won’t fail you. |
| 6.0 lb | All-Weather / Hard-Primer Ready | Firm | Strong | Best with steel-case ammo or “budget” primers. Great for suppressor use, sub-zero climates, or if your Glock’s your backup on a boar hunt. |
| 6.5 lb | Carry Gun / Max Reliability | Firmest | Strongest | If you CCW, protect others, or value reliability over feel, this is your go-to. Pair with a 3.5–4.5 connector to smooth it without risking light strikes. |
Compatible with Glock Gen 1–5.
(Not for Glock 42, 43, 43X, 48. We love them. But no.)
WHAT THE SPRING ACTUALLY DOES:
The firing pin spring (aka striker spring) controls how hard your striker hits the primer.
-
Lighter spring = lighter trigger pull but weaker ignition.
-
Heavier spring = stronger ignition but a stiffer trigger break.
That’s why spring choice affects both your trigger weight AND your reliability—especially with cheap ammo or steel-case primers.
