✅ Why Use a 9MM Recoil Tuning Kit?

The factory 8 lb spring works well for general shooting. However, different ammo loads change how your slide moves. When the spring weight matches your load, your pistol:

✅ Cycles smoother
✅ Feeds more reliably
✅ Returns to target faster
✅ Reduces frame and slide wear
✅ Feels softer and flatter in recoil

In short, your Prodigy runs better and lasts longer.

✅ Spring Weight Guide

✅ 7 lb Spring – Best for very light target loads
✅ 9 lb Spring – Great for soft competition loads
✅ 10 lb Spring – Ideal for mid‑range loads
✅ 11 lb Spring – Perfect for Major Power Factor and +P ammo

Because every shooter and load is different, this kit gives you maximum control.

✅ Increases spring life
