About this product+
ISMI Premium Springs are manufactured exclusively with certified aerospace specification alloys; chrome silicon. Then their springs are heat treated, shot-peened and stress relieved after winding to enhance performance and durability. Chrome silicon springs have 1x 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 5 mile race, a valve spring in an IndyCar will go through more than 20,5, 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.
