Spring Weights
Recoil Spring Tuner Pack, Explained
The whole range of spring weights in one buy, so you can quit guessing and let the gun pick.
What you get
The NDZ Tuner Pack bundles the full range of spring weights for your platform in one buy, instead of committing to a single weight and hoping you guessed right. It turns picking a spring from a coin flip into something you settle at the range.
Why bother testing
The right weight rides on your exact gun, your ammo, and anything hanging off the muzzle like a can or comp — variables no chart can fully call for you. Shooting it lets the gun answer: you watch ejection and lock-back across weights and let reliability make the decision.
How to run one
Start with the weight closest to your gun's stock spec, shoot your real carry or match ammo, and watch the results — brass pattern, ejection, lock-back. Slide slamming and brass flying on hot ammo? Go up a weight. Short-stroking on weak ammo? Go down. Re-shoot until one weight runs everything clean, then settle on it and prove it over a full session before you trust it.
FAQ
- What comes in the Tuner Pack?
The full range of recoil spring weights offered for your platform, so you can test them instead of committing to one weight up front.
- How do I use it to find my weight?
Start near your gun's stock spec, shoot your real ammo, and read ejection and lock-back. Go heavier if the slide over-travels on hot ammo, lighter if it short-strokes weak ammo, and re-shoot until one weight runs everything clean.
