***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.***

greatly satisfied results . Nice easy trigger pull with accurate results when shooting. I installed on Maverick 88 20 Ga. with a little difficulty because of extra spring inside trigger mechanism which is not shown in video. Maybe an adapted video should be added. Really love my shotgun now.

I really don't understand these people who say install was easy, video made it simple, works like a charm, great price, then give three or four stars? What do you want, a free six pack with it?

The only issue I had was the fact "it's much easier with the spring compression tool." I, probably like some others, didn't notice/purchase that tool. It would have been helpful to show an alternate method of assembly/disassembly.
