The deathadder is for normal sized hands, i've done far more research than what i'm willing to admit but it's the exact length for an average male to palm. The average male hand is 189mm, my hands are 215mm, which isn't that unusual, but far to large for the deathlagger.
So i'm sorry that i have to tell you this but if you're male and can comfortably palm a deathadder, you have small or normal sized hands.
