ISMI Improved P365XL / XMacro 17rd Magazine Spring

Improved P365XL / XMacro 17rd Magazine Spring

SPRING ONLY

These XMacro 17rd magazine springs are a good improvement over the stock spring.  Easier to load the full 17 rounds while still giving proper force and will last longer than the stock ones do. They are a "factory" drop in and will fit the follower and base plates as the factory springs do.
