1911 Commander Flat Wire Chrome Silicon Recoil Springs by ISMI

Manufactured from Chrome Silicon alloy to maximize spring longevity and load. These springs offer the ability to replace worn out factory parts, tune sight movement, or tune the pistol for a specific load. The benefits of switching from conventional round wire to flatwire include improved cycling, spring longevity (upwards of 50k compression cycles), and more tolerant to a wider variety of loads. Available in a variety of spring weights. This product will only function with 1/4″ diameter guide rods and compatible with most 4.0 and 4.25″ models.

Available in: 13, 15, 18, 20, and 22lb loads.
