Glock 17/34 Gen 5 – Alpha Pack Complete Spring Kit – 9mm Tuning Kit
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The IronKells Armory Alpha Pack Complete Spring Kit is built for Glock 17 and Glock 34 Gen 5 9mm pistols when you want more control over how the gun cycles, resets, and feels under recoil. Instead of being locked into one factory setup, this kit gives you multiple spring weights so you can tune the pistol around your ammo, recoil feel, and trigger preference.
This uses IronKells Armory performance trigger-system springs. The goal is simple: smoother cycling, flatter tracking, cleaner trigger feel, and a reset that feels less like dragging a boot through gravel. Classy? No. Accurate? Absolutely.
Alpha Pack Tuning Stack
Recoil springs tune slide speed. Striker springs affect trigger feel and ignition force. Trigger return helps reset authority. The safety plunger spring smooths the press. Tune one system at a time, unless you enjoy diagnosing chaos like a cursed gunsmith.
Fitment
- Fits Glock 17 Gen 5 9mm.
- Fits Glock 34 Gen 5 9mm.
- Recoil springs are intended for Glock 17/34 Gen 5 full-size recoil spring tuning setups.
- Striker springs support Glock striker spring tuning across compatible Gen 1–6 style firing pin systems.
- Trigger return spring is a 25% extra-power style for Gen 5/6 Glock pistols and Glock 42/43/43X/48-style trigger housing applications.
Does NOT Fit
- Does not fit Glock 19, 19X, 45, 26, 43, 43X, 48, or other compact/slimline models for the recoil spring portion.
- Does not fit Gen 1–4 Glock 17/34 recoil systems unless you are using a compatible Gen 1–4 guide rod/spring setup separately.
- Not recommended as a blind “drop it in and forget it” carry/duty setup. Tuned spring systems need live-fire testing with the exact ammo you plan to run.
Setup Guide / Compatibility Breakdown
| Recoil Springs — 11 lb, 13 lb, 15 lb | Controls slide speed, cycling behavior, recoil feel, and compensated / ammo-specific setups. |
| Striker Springs — 4 lb, 4.5 lb, 6 lb | Affects trigger feel and primer ignition force. |
| Trigger Return Spring — 25% Extra-Power Style | Helps sharpen reset feel and trigger return authority. |
| Safety Plunger Spring — Reduced-Power Style | Helps smooth the trigger press through the firing pin safety plunger movement. |
Note: Recoil and trigger tuning depend on the full setup, including ammo pressure, compensator design, slide mass, optic weight, striker condition, connector geometry, lubrication, and break-in. Live-fire testing is mandatory.
What It Does
This kit lets you tune the major spring forces that affect slide speed, recoil feel, trigger weight, ignition force, and reset. The recoil springs help control how fast the slide cycles. The striker springs help adjust trigger feel and primer ignition force. The trigger return spring helps sharpen reset feel. The reduced-power safety plunger spring helps smooth the trigger press without removing the factory safety system.
Why It’s Worth It
Factory Glock springs are built to work acceptably across a wide spread of ammo, shooters, and conditions. That is reliable, but it is also a compromise. The Alpha Pack gives you room to tune the gun around how you actually shoot. Start with the recoil system first, then work through striker and trigger feel. If slide speed is wrong, everything else starts lying to you.

Install Notes
- Tune one system at a time.
- Do not throw every light spring in the gun and then wonder why the pistol acts possessed.
- Start with the recoil spring, test function, then move into striker and trigger spring tuning.
- Reduced-power striker springs can improve trigger feel, but they may also reduce primer ignition force.
- Always test with the exact ammo you plan to use.
Striker Spring Guidance
- The 4.5 lb spring is usually the best balance of lighter feel and reliability.
- The 6 lb spring favors stronger ignition.
- The 4 lb spring should be treated as a range/competition tuning spring and tested hard before trusting it.
Verify Before You Buy
- Verify that your pistol is a Glock 17 Gen 5 or Glock 34 Gen 5 before ordering.
- The recoil spring portion of this kit is the fitment-critical part.
- Full-size Glock recoil systems are not the same as compact or slimline recoil systems.
- After installation, function test the firearm unloaded, then live-fire test with your actual ammo before carrying, competing, or relying on the setup.
