I started with:
Colt Python 6"
S&W 29-1/29-2 6 1/2" (Dirty Harry)
I later ran into a Colt Model 1917 for a good price. It didn't make my list, but it's in my safe.
Maybe the Blackhawk SA .45 should have been on the list, but it's in my safe.
I came with a hair of buying a S&W commerative Classic. I just couldn't stomach $1,350 for a "fake".
The very next month, an ad popped up for a 1978 S&W 6 1/2" 29-2 for $800. Also in my safe.
There is no real active hunt for the Python, but when the right one comes along...
