Sig P320 Chrome Silicon Mag Spring for 17 & 21 Round Magazines by ISMI

Manufactured of Chrome Silicon alloy these plus power magazine springs are designed to provide more load and last longer than the factory equivalent. The advantage of Chrome Sil in a magazine spring is its higher yield point of material, allowing for the spring to take less initial “set” and provide a greater load while being under less stress.
