A Green spring means it has a +p rated spring for the hotter 45acp rounds . A grey box usually came on the west german sigs some say better quality if I remember correctly.
just bought a used p220. was told it is a "gray box, green spring". what does this mean. heard its more desirable, but why. just curious. thanks

The green spring is current production in the P220 and rated 20lbs. Previous models had the black spring rated at 15-16 lbs.
