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.

Note: NDZ always recommends any part be installed by a qualified and trained gunsmith. NDZ promotes the use of safety practices and gear when working on any firearm.
