I never really found a deagle to be uncontrollable.
Stupid gun? Yes. Hard to shoot? No.
IMHO dat Deagle is the kind of gun where you really need to just shoot somebody else's and then within about 24 rounds or so you will either reach one of two conclusions.
A. "This gun is fun to shoot but it's still f***ing stupid, so im not buying one"
Or
B. "I NEED DIS gun in muh lyfe, nao!"

I went with A and saved myself 1500-2grand.
Mileage may vary. I suggest bribing a DE owner to try theirs before buying.
