In it's day,... for looks, and looks alone, I couldn't go past the .44 Automag, but since then, I've had a bit of a love affair with my old Colt Python, with 6" barrel.
I never owned an Automag or even saw one in the flesh, they were poisonously expensive at the time with about a six month waiting list, plus the fact that things used to fall off them when they were fired, sorta cut short my initial enthusiasm.
The Python was a pig to shoot (accurately) until I bought myself a set of good rubber grips, as I have short stumpy fingers.
