Does the grip attachment actually do anything? I have tried it on pretty much every gun in the game and i cant tell any diffrence, the recoil dosent really bother me im just curious to know. And if it effects some guns and not all then witch ones are those?
According to Treyarch, it reduces the amount of time a weapon needs to recenter after firing. In that case, it's effects would be most noticeable on semi-automatic and burst-fire weapons, allowing you to spam the trigger a little faster while still maintaining accuracy.
For a fully automatic gun, it would only help if you were burst-firing the weapon.
