✅ Prodigy Recoil Spring – Flat Wire – 10 Pound – Commander

Keep your Springfield Armory Prodigy 4.25 running smooth and reliable with this original ISMI 10 lb flat wire recoil spring. ISMI builds this spring as the exact replacement for the EGW SA Prodigy Commander guide rod kit. It is the same spring that ships with the EGW rod, so you get the perfect factory match every time.

This flat wire design delivers smooth slide movement, steady control, and long service life. Because flat wire springs spread stress across more surface area, they last longer than standard round wire springs. As a result, your Prodigy cycles cleanly and stays consistent through high round counts.

The 10 lb spring works best with 9mm Prodigy and Commander-length 1911 pistols. It balances recoil control with easy slide movement. Therefore, it supports fast follow-up shots, smooth feeding, and reliable lockup.

However, this spring only fits Commander 1911s with a full-length 1/4″ diameter guide rod. It will not work with standard-diameter guide rods or short guide systems.
