***If you have a Mossberg 590, then you will need to remove both hammer springs that are in the Mossberg 590 Trigger Group from the Factory. There is an inner and outer hammer spring that fit inside one another. Then replace the 2 factory springs with the single M*CARBO Hammer Spring in this kit. We've thoroughly tested this to ensure it would be free from light strikes or discharges when dropped. Due to the Mossberg 590 being used by the Military, it includes 2 hammer springs from the factory to ensure it will ignite harder primers on military grade ammo. Unless you are shooting military grade ammo you will not experience any light strikes.***

Better than stock!

Cons:
Striker spring seems to be the same stiffness as the stock spring, however much longer. So the hammer hits the pin a lot harder. The trigger return spring seems to be the same stiffness and length as stock. I don't have a pull gauge, so not sure if there was a change in pull. The videos that Chris puts out make things pretty easy to do it yourselfer. My order had been received two days earlier than expected.
