Frequently Asked Questions

What does the 14lb rating mean? It is the recoil spring’s weight rating; a heavier or lighter rating changes how stiffly the slide is pushed back into battery, which shooters tune to their load and barrel length.

Why choose a flat-wire spring over round wire? A flat-wire spring is built with a flatter force curve through its compression stroke than a round-wire spring, which many 1911 shooters prefer for more consistent recoil feel.
