Glock 17/34 Full Size – Recoil Spring – IronKells Armory Flat Wire – 11 lb / 13 lb / 15 lb
PLEASE DOUBLE CHECK DETAILS, GUIDE ROD TYPE, AND FITMENT BEFORE PURCHASE.
This IronKells Armory flat-wire recoil spring is built for compatible full-size Glock-pattern pistols, with this listing focused on Glock 17 and Glock 34 size setups. It gives you a cleaner way to tune slide movement, cycling feel, and recoil behavior without treating spring weight like a coin toss.
Available in 11 lb, 13 lb, and 15 lb options, these springs are for shooters tuning around ammo choice, compensators, competition setups, or recoil preference. This listing is for one individual recoil spring in the selected weight. It is not a complete recoil spring assembly and does not include a guide rod.
Variants / Options
- 11 lb: Light-load / competition-style flat-wire tuning spring
- 13 lb: Balanced tuned flat-wire setup
- 15 lb: Mild tuning / closer-to-stock flat-wire behavior
Fitment
- Fits compatible full-size Glock pattern models including Glock 17 and Glock 34.
- Retailer-supported full-size fitment commonly also includes Glock 17L, 20, 21, 22, 24, 31, 35, and 37 platforms using the same full-size spring family when the guide rod system matches this spring profile.
- Best customer-facing fitment for this listing: Glock 17/34 full-size setups.
- Designed for compatible flat-wire full-size guide rod systems.
- May fit compatible captured or non-captured / uncaptured guide rods when the guide rod shaft, spring seat, end cap, and retaining cap are designed for this flat-wire spring profile and diameter.
Does NOT Fit
- Does not fit compact, subcompact, slimline, or large-frame Glock models unless specifically confirmed compatible with the same full-size flat-wire spring family.
- Does not include a guide rod or complete recoil spring assembly.
- Does not fit factory Glock dual recoil spring assemblies unless specifically confirmed compatible.
- Does not fit round-wire-only guide rods or guide rod assemblies.
- Does not fit any guide rod where the shaft, spring seat, end cap, or retaining cap is not designed for this flat-wire spring profile and diameter.
- Do not assume Gen 4 or Gen 5 dual recoil spring assembly compatibility unless your pistol has the proper conversion parts and guide rod setup.
Setup Guide / Spring Weight Breakdown
| 11 lb | Light-load or competition-style tuning option. Best for carefully tested setups and may be too light for some ammo or duty-style use. |
| 13 lb | Balanced middle-ground choice for tuned full-size builds, compensated setups, or lighter-recoiling range configurations. |
| 15 lb | Mild tuning option that stays less aggressive than 11 lb or 13 lb. Still lighter than the 17 lb stock full-size Glock recoil spring reference. |
Note: Recoil tuning depends on the full setup, including ammo pressure, compensator design, slide mass, optic weight, guide rod type, grip, lubrication, and break-in. Live-fire testing is mandatory.
Guide Rod Compatibility
This is a flat-wire recoil spring. It is designed for compatible full-size Glock guide rod systems that accept this flat-wire spring profile and diameter.
This spring may be used with compatible captured guide rod assemblies or compatible non-captured / uncaptured guide rods, but the guide rod shaft, spring seat, end cap, and retaining cap must match the spring profile. Flat-wire and round-wire recoil springs are not automatically interchangeable.
What It Does
This spring controls slide return and cycling behavior. Changing recoil spring weight can affect slide velocity, timing, felt recoil impulse, and how the pistol behaves with lighter loads, hotter loads, compensators, or other tuned parts. In plain English: this is one of the parts that directly changes how your Glock runs.
Why It’s Worth It
The value here is practical tuning control. If you are replacing a worn spring or tuning a full-size Glock build, this gives you a clean IronKells Armory flat-wire option instead of rolling the dice on mystery metal. Pick the weight, test the ammo, and let the gun tell the truth.

Install Notes
- This is a recoil spring only, not a complete captured guide rod assembly.
- Reduced spring weights like 11 lb, 13 lb, and 15 lb are usually chosen for tuned setups and may not behave the same as stock with every ammo type or pistol configuration.
- Do not install this spring on a round-wire-only guide rod or any guide rod that does not properly seat this flat-wire spring profile.
- Function test your setup, and do not trust any tuned recoil setup for serious use until you have actually run it.
Verify Before You Buy
- Verify your exact Glock model, frame family, generation, and guide rod compatibility before ordering.
- Verify that your guide rod is designed for flat-wire recoil springs.
- Verify whether your setup is stock, compensated, competition-tuned, or ammo-specific.
- Flat-wire and round-wire recoil springs are not automatically interchangeable.
- Recoil spring weight is not a random decoration. Picking the wrong one can create reliability problems fast.
