P365-XL Magazine Springs
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.
These 17 round mag springs are specifically designed with tighter tolerances to allow the coils to "nest" correctly. This provides greater load and overall longevity while still allowing to load all 17 rounds without hassle.
Any warranty issues with this product must be handled directly with ISMI Springs. (Manufacturer's Warranty)
