Description:

If you want a crisper more positive trigger rest with your P320 the ISMI +10% power Trigger Return Spring is a great upgrade over the stock spring.

With the ISMI Plus 10% Trigger return spring does not add any weight to the trigger pull but makes a noticeable difference in the trigger reset. With this ping installed you get a much more tactical and audible reset with your P320 Trigger.

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 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.
