Sig Guy Redesigned P365 XMACRO 17 Round Magazine Spring
 
 SPRING ONLY. FOLLOWER, FLOOR PLATE AND MAGAZINE BODY NOT INCLUDED 
 
Product description:
These redesigned xmacro magazine springs not only last longer than the factory springs they also make loading all 17 rounds much easier. Instead of the spring coils stacking up on top or each other ours collapse more inside each other. This allows the spring to compress more making loading easier and because the material is improved they also improve on the force as well as the longevity. OEM magazine body and follower are reused. Replace your factory springs with our springs and your thumbs will love you for it.
