P320 Extra Power 17 Round Magazine Spring (+10%)


These premium springs are manufactured in the USA from chrome silicon wire, which are then heat treated, shot-peened and stress relieved after winding to enhance performance and durability.


Chrome silicon springs have 10x the life of traditional music wire springs, and they hold much better tolerances during compression and cycling.


Excellent for use with extra capacity base pads, or as a replacement for a worn-out factory spring. Can also be used as a direct replacement when extra capacity base pads are NOT being used.  Please note that magazines equipped with plus-power springs (especially magazines without extended base pads) may require a break-in period to be able to load the magazine to full capacity.


ONLY for use with 17rd magazines that come with these following models in unrestricted states:
