About this product+

This ISMI 20lb Recoil Spring fits Glock Models G19, G23, G25, G32, 38 - Compact 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.

    Best recoil springs available IMHO

    These ISMI recoil springs are, in my opinion, the best you can get for the Glock pistols. It is very nice to be able to change to different weight springs to work better with different loads.

    Seemed good

    seemed to be a good quality spring but wouldn't fit on my match guide rod so its trashed now. So just make sure you know it will fit the guide rod you are buying it for before you buy it.

    Great spring for +P+

    Great spring for higher power rounds. The fit for a G19 Gen5 was perfect.

    Product is great but...

    The product was just as expected but for some reason the website is extremely hard to navigate and makes for a frustrating experience.
