ISMI plus power magazine springs are designed to provide more load and last longer than the factory equivalent. The advantage of Chrome Silicon 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.
COMPATIBLE WITH Sig Sauer® P365® pistols.
Manufactured from Chrome Silicon alloy to maximize spring longevity and load.
Available in 10 and 12 round variants.
