About this product+

This ISMI 17lb Recoil Spring fits Glock Models G17, G17L, G20, G21, G22, G24, G31, G34, G35, G37 - Full Size ONLY.

ISMI Premium Springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then their springs are 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.

These springs utilize the same design and manufacturing technology as used in IndyCar and Formula One racing. In a typical 500 mile race, a valve spring in an IndyCar will go through more than 2,500,000 compression cycles. Consideration of factors such as modulus, wire diameter, mean diameter, active coils, total deflection, spring relaxation, maximum service temperature, and operating environment, results in you having modern spring technology available for your pistol.

    Great Springs

    After purchasing 3 springs and a guide rod from NDZ Performance, I am very satisfied. When I am in need for more, this company has my business. Thanks!

    Great Replacement Spring

    Completely happy with the factory style, flat ISMI 17lb spring. Use in place of your factory 17/18lb spring to replace a worn factory spring at 5k’ish

    I come to NDZ Performance for a lot when I need parts for my Glock pistols. Their guide rods, springs, slide release levers and much more are awesome. To top it off the prices are very competitive and shipping over $20 is free. Hard to beat.
