ISMI Recoil Spring for NDZ Glock 43 43X 48 Guide Rod

ISMI Flatwire Premium Springs are manufactured from Chrome Silicon alloy, and are available in a variety of weights to allow for exact tuning of the sight movement, overall feel, and load tolerance of your firearm. You can choose your spring weight from our range of options to decrease, increase, or maintain the stock weight (17lb). Their springs are heat treated, shot peened and stress relieved after winding to enhance performance and durability for maximum longevity. Chrome silicon springs have 10x the life of traditional music wire springs, and they hold much better tolerances during compression and cycling. Upgrade your firearm with an ISMI guide rod spring to get the best performance in every shot.

  • Comes in 3 different weights so you can tune the feel of your firearm: 17lb (Stock), 15lb, & 19lb.
  • Made in the USA from durable chrome silicon.
  • Designed to only work with single spring guide rods for the Glock 43, 43X, & 48.
